Claims

[Scope of utility model registration request]

In a pump device equipped with an eccentric ring that forcibly pops out a vane, the eccentric ring provided in the housing forms an obtuse angle between the sliding surface with the vane and the end surface of the eccentric ring, and the vane A pump device characterized in that the angle between the sliding surface of the eccentric ring and the end face of the vane is formed into an obtuse angle similar to the angle of the eccentric ring.
