A refrigeration cycle apparatus has a compressor, a condenser connected to the discharge side of the compressor, an evaporator connected to the suction side of the compressor, a decompressor connected between the condenser and evaporator, and a valve of a pressure responsive type. The valve includes a housing having a chamber, and a valve piston slidably received in the chamber. The suction side of the compressor is connected to the chamber through a first communication port of the housing and the discharge side of the evaporator is connected to the chamber through a second communication port of the housing. The discharge side of the condenser is connected to the chamber through a first guide port of the housing and the discharge side of the decompressor is connected to the chamber through a second guide port of the housing. The valve piston has a first communication passage for communicating the first and second communication ports, and a second communication passage for communicating the first and second guide ports.
