Fluid compressing apparatus for compressing, pumping and discharging fluid, has fluid discharge ports which are opened through movement of valve piston as pressure of fluid in cylinder bore reaches predetermined value

摘要

Fluid is drawn as a fluid suction port (130) is selectively opened by a piston (200) reciprocating in a cylinder bore (110), and is discharged through the fluid discharge ports (150) of a cylinder block (100). The fluid discharge ports are opened through the movement of the valve piston (310) as the pressure of fluid in the cylinder bore reaches a predetermined value.
