Suction valve, pressure boosting pump, and hydrogen supply system

Abstract

A suction valve, a pressure boosting pump, and a hydrogen supply system include a block having a compression chamber and a recess communicating with the compression chamber, a valve casing housed in the recess and forming a first space part communicating with the compression chamber, a pressing member pressing the valve casing against the block, a suction channel provided in the valve casing and sucking a low-temperature fluid to the first space part, a first discharge channel provided in the valve casing and discharging gas in the first space part, a first valve body capable of causing the compression chamber and the first space part to communicate with each other and capable of isolating the compression chamber and the first space part from each other, a second valve body capable of causing the first space part and the first discharge channel to communicate with each other and capable of isolating the first space part and the first discharge channel from each other, and a second discharge channel discharging gas in the first discharge channel outside the pressing member.
