凍機の給排気装置。 A cylinder, a displacer that reciprocates within the cylinder, first and second variable volume spaces defined inside the cylinder by the displacer, and a gas flow that communicates these variable volume spaces. In a cryogenic refrigerator consisting of a regenerator disposed in a road, a compression device, and an air supply/exhaust device that alternately communicates the air supply/exhaust port of the cylinder with a high pressure line and a low pressure line of the compression device, the air supply/exhaust device is A hollow guide box, high-pressure line communication holes bored in two opposing walls of the guide box, a supply/exhaust port communication hole, and a low-pressure line communication hole, housed inside the guide box, and supply/exhaust ports. The slide valve body is provided with a slide valve body that reciprocates while contacting a wall surface in which a port communication hole and a low pressure line communication hole are drilled, and the slide valve body has a slide valve body for communicating the supply/exhaust port communication hole and the low pressure line communication hole. An air supply and exhaust system for a cryogenic refrigerator characterized by having a void space.
