Claims

[Scope of utility model registration request]

A piston part at one end of the rotary valve is tightly fitted into a cylinder part formed at one end of the rotary drive shaft so as to be able to slide in the axial direction and transmit rotational force, and the sealing surface at the other end of the rotary valve is tightly fitted. , the valve seat body has an inflow communication hole drilled in its center and a large number of small diameter outflow communication holes drilled around it in an arcuate arrangement. These valve seat bodies and A manifold is rotatably fixed to the casing, and a radially long communication groove is formed in the sealing surface of the rotary valve to temporarily communicate the inflow hole with the outflow hole during one rotation of the rotary valve, and A rotary valve characterized in that a communication hole is bored in the communication groove of the rotary valve to communicate an inflow hole with the inside of the cylinder part.
