Abstract

PURPOSE: To reduce power loss by inserting a central post in a cylinder with an exhaust outlet and an intake inlet so as to slide and fitting a coil spring which is connected to a drive mechanism to the central post.
CONSTITUTION: A central post 8 is coaxially inserted in a cylinder with an exhaust outlet 20 and an intake inlet 21 so as to slide and a coil spring 11 which is connected to whose one end is connected to a rotary drive shaft 14 is fit to this central post 8. When pressured oil is introduced from an oil port 19, the central post 8 is positioned at the place where the hydraulic pressure which is applied to an oil chamber 18 and the load of the coil spring 11 are balanced and the volume of a variable capacity pump chamber 13 is determined. As a result, since the exhaust rate of the variable capacity pump can be adjusted as requested, power loss can be reduced.
