Claims

[Scope of utility model registration request]

A main body block equipped with an inlet port, an outlet port, and an exhaust port, and a pair of cylinders sandwiching the main body block, and pistons that reciprocate within these cylinders are connected to each other by a rond that penetrates the main body block in an airtight manner. The main body block is equipped with an inlet check valve that only allows fluid to flow from the inlet port into each pressure increasing chamber inside both pistons, and an inlet check valve that only allows fluid to flow from each pressure increasing chamber to the outlet port. and a switching valve that switches and communicates each driving chamber on the outside of both pistons with an inlet port and an exhaust port, and a push rod for switching the switching valve is connected to each pressure increasing chamber by a push rod spring. At the same time, a non-acting sliding gap for the push rod is provided between each inner end of the push rod and the end face of the spool and the lever of the switching valve, and the inlet check valve is biased by an inlet check valve spring. Features a pressure booster.
