Operating process according to the reciprocal compressor of a preferred embodiment is explained as follows.
Piston 142 is under the driving force effect of reciprocable machine 30, and is reciprocating in cylinder 141, changes the volume of pressing chamber P, thereby sucks gas to pressing chamber P and compress.
When gas pressure was higher than a certain setting pressure, discharge valve assembly 170 was opened, and discharges out pressurized gas.This process repeats along continuous.
Definite says, when piston 142 moved to lower dead centre (a), discharge valve assembly 170 stopped the pressing chamber P of cylinder 141, and the switch sections 143c that links to each other with piston 142 on the suction valve 143 turns up, so suction passage F opens.At this moment, gas is inhaled into the pressing chamber P of cylinder 141 by the suction passage F of piston 142.
