- a housing part of the fuel pump is formed on a connection head for the fuel filter, and thereon a lid is fixed by means of a retaining ring. Between the housing lower part and the cover, the peripheral edge of a membrane is clamped, which extends substantially along the inside of the lid, wherein the central region of the membrane between the lower plate of a knob and a support plate is clamped.
- the knob itself consists of two components which are to be supplied to the lid during assembly of different sides and are connected by latching when nesting the two knob parts.
- a reciprocating pump has already been proposed in which a pump piston is arranged in a hollow cylinder formed by a pipe.
- This pump piston comprises a plate-shaped bearing and a closure element received therein, which is provided at its outer edge with a sealing lip. It is important that the sealing lip is mounted in a form-fitting adapted annular chamber.

- Piston rod is arranged a coaxial with the ring extending pin on which the middle part of the seal is attached.
- the middle part of the seal has a passage opening through which the pin projects, and at the front end of the pin, a truncated cone is formed, through which the seal is fixed on the pin.
- an existing plastic sleeve is attached to the housing, through which the piston rod protrudes from the housing and in which the piston rod is sealingly guided.
- the sleeve has a radial flange, wherein this flange is connected to a contact surface with the housing by ultrasonic welding or gluing.
- a sealing ring is arranged, which surrounds the piston rod sealing and is supported on the side to the pumping chamber by means of a disc. Such a seal prevents the escape of fuel along the piston rod.
- the piston rod and the handle are made in one piece.
- the pumping chamber is connected to a suction port and a pressure port by means transverse to the longitudinal direction of the pumping chamber in the housing extending channels.
- the bore is preferably designed as a blind hole, and the channel to the pressure port is provided at the inner end of the bore, so that in an end position of the piston, a free passage between the suction port and the pressure port is formed.
- Design may be a locking device for fixing the
- Piston rod may be provided in the end position of the piston. hereby
- the locking device can

- Plastic existing housing 2 comprises, in which one as a blind hole
- the bore 3 forms a
- a suction port 4 is provided in the housing.
- the channel 5 near an outer end of the
- Pressure port 6 is arranged, which by means of a channel 7 with the bore
- a piston 9 is mounted longitudinally displaceable, wherein the
- Piston 9 is fixed to a piston rod 11, with its the piston
- the piston rod 11 are made of plastic. On the piston 9 is on the piston 9
- Fig. 1 the piston 9 is in its uppermost position, d. H. at maximum volume of the pumping chamber P. With H the stroke of the piston 9 is indicated, as is apparent from the arrows. During the pumping process, the maximum stroke H between an upper position o and a lower position u is given.
- a sleeve 13 is arranged, which serves to guide the piston rod 11.
- the sleeve 13 has on its outer periphery a flange 16 which is located on a contact surface of the housing 2 and is fixedly connected thereto. Also, the sleeve 13 and the integrally formed with this flange 16 are made of plastic. For solid connection of the flange 16 with the housing 2, in particular ultrasonic welding or gluing come into consideration.
- a sealing ring 14 On the bore 3 closing side of the sleeve 13 is a sealing ring 14 which is supported towards the hole 3 through a disc 15 and the piston rod 11 surrounds sealing.
- the piston rod 11 has at its outer end a handle 12 for manual actuation of the hand pump 1.
- the handle 12 is made in one piece with the piston rod 11 and thus also consists of plastic.
- an external thread 17 is provided on the piston rod 11. Accordingly, the sleeve 13 is provided with an internal thread 18, so that the piston rod 11 and thus also the piston 9 at 9/17 3143
- Non-use of the hand pump 1 in a certain position can be fixed, that the piston rod 11 is screwed with its external thread 17 in the internal thread 18 of the sleeve 13.
- FIG. 2 shows a section through the hand pump 1, which corresponds to the illustration in FIG.
- the reference numerals correspond to those of FIG. While in Fig. 1, the piston 9 is shown in its maximum uppermost position o of the stroke H in the bore 3, the piston 9 is in Fig. 2 in its lowest position u of the pumping stroke H.
- the pumping function is only an alternating longitudinal movement of the piston 9 between upper position o and lower position u.
- a sealing lip 22 is provided on the outer circumference of the seal 10, which due to its elasticity can be applied to the wall of the bore 3 or can also be raised therefrom by a radial gap between the bore 3 and the piston 9 and the seal 10 release.
- the sealing lip 22 is located on the wall of the bore 3, so that the volume in the pumping chamber P is reduced and a corresponding amount of fuel from the pumping chamber P is conveyed through the channel 7 to the pressure port 6, on the other parts a fuel supply system are connected.
- the sealing lip 22 lifts off from the wall of the bore 3, 10/17 3143 so that fuel from the suction port 4 can flow into the pumping chamber P.
- the sealing lip 22 thus fulfills the function of a check valve.
- Fig. 3 shows an exploded view of the insertable into the housing parts, which essentially comprise the piston 9 with piston rod 11 and sleeve 13 for guiding the piston rod 11.
- the handle 12 and the piston rod 11 are made in one piece, including the external thread 17.
- annular groove 23 is provided at a distance from the lower end of the piston rod 11.
- a pin 24 is frontally formed and thereon a truncated cone 25, the base surface is greater than the cross section of the pin 24 and the tapered end of the piston rod 11 facing away.
- the sleeve 13 is shown with its flange 16 and below the sealing ring 14 and the disc 15. Below this, in turn, the piston 9 is located with the seal 10.
- the piston 9 is formed by a ring 20 on which distributed over the circumference several - in the embodiment four - extending in the axial direction arms 21 are formed. At the free ends of the arms 21 radially inwardly directed locking lugs 26 are provided.
- the sealing ring is inserted into the corresponding recess of the sleeve 13 and the piston rod 11/17 3143
- Fig. 4 is a section through the hand pump 1 shown in FIG. 1.
- the reference numerals correspond to those of FIGS. 1 to 3.
- the piston 9 is in a position at the inner end 8 of the bore 3, wherein the sealing lip 22 of the seal 10 a passage for the fuel from the pumping chamber 12/17 3143
- FIG. 5 shows an enlarged view of the detail V in Fig. 4. It can be seen that the sealing lip 22 is below the upper edge of the channel 7 and thus a free passage 28 is given for the fuel. It is also apparent from Fig. 5 that the locking lugs 26 engage the arms 21 in the annular groove 23 on the piston rod 11.
- the ring 20 has radially inwardly directed projections 27, by which the piston 9 is supported at the front end of the piston rod 11. Incidentally, the reference numerals for the same parts with those of Figures 1 to 4 coincide.
- a radial shoulder 29 is provided on which the disc 15 abuts, which serves to support the sealing ring 14 .
