Claims

[Scope of utility model registration request]

, a piston that is housed in a cylinder and compresses refrigerant gas during operation; a motor chamber that houses a motor that drives the piston via a crankshaft; a crank chamber in which the crankshaft is housed and lubricating oil is stored at the bottom; a partition wall that partitions the suction passage and the crank chamber; a pressure equalization valve that equalizes the pressure between the suction passage and the crank chamber, which has an air passage communicating with the gas phase part of the chamber and a valve that opens and closes this air passage; A refrigerant compressor comprising an oil hole that communicates with a gas phase portion of the crank chamber and guides oil in the suction passage into the crank chamber.
