に、該スライダ間にスプリングを縮設した、 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 pistons reciprocating within the cylinders are connected to each other by a rod that penetrates the partition wall in an airtight manner. An inlet check valve is connected to the partition wall and allows fluid to flow only from the inlet port into each pressure increasing chamber inside both pistons, and an inlet check valve only allows fluid to flow from each pressure increasing chamber to the outlet port. In a device equipped with an outlet check valve 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 for switching the switching valve is connected to the end of each pressure increaser. It is characterized in that it is configured as an integral piece projecting into the room, and a pair of sliders for switching the position of the switching valve are slidably inserted into the push rod, and a spring is compressed between the sliders. Pressure booster.
