Abstract

PURPOSE: To stabilize a discharge water pressure for precise adjustment by an arrangement wherein a notch on valve port side of a check valve and a notch on valve side are adjusted to be ready for mating by operating an adjusting knob.
CONSTITUTION: Water sucked through an inlet port 84 by reciprocation of a piston is fed into a discharge space 26 through a clearance produced between a check valve 85 and a valve port 89. Then, a by-pass channel connecting an inlet space 27 and the discharge space 26 is formed by operating an adjusting knob 98 to turn the check valve 85 and thus mating a notch 91 on valve port side of a valve port 89 with a notch 92 on valve side of the check valve 85, and the inlet space 27 and the discharge space 26 are disconnected by turning the check valve 85 to move the notch 92 to a counter side of the notch 91. thus a discharge water pressure can be adjusted arbitrarily by adjusting a mating area for both notches 91, 92 according to a movement of the check valve 85 through operation of the adjusting knob 98.
