Abstract

PURPOSE: To facilitate suction compression working of refrigerant gas even if revolution of a rotor may become either right or left direction in such a way that two discharge valves and two suction valves are provided, and two suction ports are short-circuited.
CONSTITUTION: In case where the revolving direction is in direction C, flow of refrigerant comes through a suction pipe 35, via a suction pipe 30 which is connected to a suction pipe 33 at a short-circuited point 34, a suction valve 29, and a suction port 28 into a cylinder chamber 25, a contact point 27 comes to the left side as shown in the figure of a slider 20 by revolution of a roller 22 when the cylinder chamber 25 performs compression working, and air is exhausted through a discharge valve 24 into the space 19 of a vessel. In this case, a suction valve 32 is closed by pressure difference. Then, in case where the revolving direction is in direction D, flow of the refrigerant comes through a suction pipe 35 via the suction pipe 33, the suction valve 32, and a suction port 31 into a cylinder chamber 26, and when the roller 22 has a turn, air receives compression working, and it is exhausted through a discharge valve 23 into the space 19 of the vessel. In this case, the suction valve 29 is closed. Thus, in either right or left direction for revolution of the roller 22, it functions as an enclosed refrigerant compressor.
