Abstract

PURPOSE: To make fluid pressure adjustable, simplify structure and reduce the number of components, by fitting a pressure control valve in a discharge passage, being held by a valve seat which receives suction and discharge valves, and attaching a pressure adjusting unit to a cylinder.
CONSTITUTION: A suction passage 8a, discharge passage 8b and valve devices 9 are fitted to the tip of a cylinder 5 which supports freely reciprocating plungers 7, and the valve devices 9, suction valves 92 and discharge valves 93 are actuated by the reciprocating motion of the plungers 7. A valve seat 91, receiving at least one of the suction valves 92 and discharge valves 93 respectively, holds a pressure control valve 11 which is fitted to the discharge passage 8b for pressing the valve seat 91 by virtue of a control spring 12. A pressure adjusting unit 13 for holding the control spring 12 is set movable to the cylinder 5.
