ストンを、摺動可能に嵌挿した、 ことを特徴とする増圧装置。[Claims for Utility Model Registration] A partition wall having an inlet port and an outlet port, and a pair of cylinders sandwiching the partition wall, and a piston that reciprocates within the cylinders is driven by a rod that penetrates the partition wall in an airtight manner. An inlet check valve that is connected to each other and is provided on the partition wall to allow fluid to flow only from the inlet port to each pressure increasing chamber inside both pistons, and an inlet check valve that only allows fluid to flow from each of the pressure increasing chambers to the outlet port. and a switching valve that switches each drive chamber on the outside of both pistons to an inlet port and an exhaust port for communication. The push rod is configured as an integral part that protrudes into the room, and has an enlarged diameter section formed at the end of the push rod that airtightly penetrates the push rod guide between the switching valve and the pressure intensifier chamber, and is formed on the pressure intensifier chamber side. 1. A pressure increase device comprising: a detent piston slidably inserted into the detent piston to support the push rod by applied fluid pressure.
