装置。 A valve body that has a valve chamber that communicates with the high pressure side of the compressor via a high pressure introduction passage, a passage that communicates with the valve chamber via an opening having a valve seat, and that communicates the high pressure side of the compressor with the low pressure introduction passage. a valve body provided in the valve chamber and opposed to the opening by a spring; a spring receiver having a slit extending in the axial direction on its peripheral edge; A cylindrical spring case in which another spring is inserted to deflect the valve body against the elasticity of the spring, and one side is open to the high pressure introduction passage, and the inside is always deflected toward the high pressure introduction passage due to the spring pressure. A pressure control device for a compressor, comprising a cylinder having a spool valve, and a bypass port in the cylinder, one of which communicates with the high pressure side of the compressor and the other with the low pressure introduction passage, and which is opened and closed by the spool valve. .
