47 The discharge valve hole 50 at the lower end opens, so that the pipe portion 42 and the flow channel 5
5, and the pressurized liquid is ejected from the nozzle hole through the space between the second cylinder 41 and the third cylinder 46. Pressing head 48
Release the second compression spring as shown in the right half of Fig. 1.
By pushing up 58, the actuator 45 first rises, the tubular piston comes into contact with the upper surface of the shoulder thereof, and the discharge valve hole 50 is closed.
The tubular valve body 51 is capped by the subsequent rise of the actuator.
The actuator stops in contact with the lower surface of the top of 20. In this way, the actuator rises even after the discharge valve hole is closed, and the piston 57
The internal volume of the upper third cylinder 46 expands, and the negative pressure causes the liquid remaining in the nozzle holes to be sucked back.
