Abstract: The present invention pertains to a four-way reversing valve for a high capacity reversible heat pump compressor. The valve comprises a housing with four ports, namely a discharge port, a suction port, an evaporator port and a condenser port. It further comprises a conically shaped rotor provided rotatably inside the housing for varying flow paths between the four ports, wherein a large diameter face of the rotor comprises two separated openings, wherein a first opening fluidly connects the large diameter face to a small diameter face of the rotor via a first fluid conduit and a second opening fluidly connects the large diameter face to a radially outer portion of the rotor via a second fluid conduit. The invention also pertains to a set comprising two or more four-way reversing valves.
