A pump body assembly and compressor

Abstract

The application provides a pump body assembly and a compressor. The pump body assembly comprises a cylinder assembly, a sealing element arranged at both ends of the cylinder, and a working chamber formed between the sealing element and the inner circle of the cylinder. The cylinder is provided with a control chamber, and a side wall of the control chamber is provided with an enthalpy-increasing channel communicated with the working chamber. A high-pressure guide channel is arranged on the side wall of the working chamber, and one end of the high-pressure guide channel is arranged on the side wall of the working chamber, and the other end of the high-pressure guide channel is arranged on the side wall of the control chamber. A control valve is arranged in the control chamber, and the control valve has a closed position for closing the enthalpy-increasing channel and the working chamber, and the control valve has an open position for connecting the enthalpy-increasing channel and the working chamber. A roller is arranged in the working chamber, and the roller has a plugging position for plugging the high-pressure guide channel and the working chamber, and the roller has a avoiding position for avoiding the high-pressure guide channel to connect the high-pressure guide channel and the working chamber. The problem that the communication between the enthalpy-increasing port and the suction port affects the suction is solved.
