The present disclosure provides a compressor and an air conditioner having the same. The compressor includes: a main shaft with a convex portion and a slip sheet; a cylinder; and an air inlet and outlet device including a disk body and an air suction port including an outer side, an inner side and a connecting side located between the outer side and the inner side, wherein the outer side is overlapped with an inner wall of the cylinder or is located on the inner side of the inner wall of the cylinder, the inner side is overlapped with an outer wall of the convex portion or is located on the outer side of the convex portion, and the connecting side is overlapped with a side wall of the slip sheet or is located on the inner side of the side wall of the slip sheet.

Air conditioner having compressor including curved suction port and a plurality of exhaust ports

A pump body assembly and a compressor with the pump body assembly. The pump body assembly includes: an oil supply passage for circulating oil; and two back pressure members, at least one of the two back pressure members being provided with a back pressure groove, the back pressure groove including a first groove section and a second groove section, the first groove section and the second groove section are disposed at intervals, the first groove section communicating with the oil supply passage, the second groove section communicating with the oil supply passage, wherein the communication area of the first groove section and the oil supply passage is a, the communication area of the second groove section and the oil supply passage is b, and a&#x3c;b.

Oil supply to the back pressure groove of a vane pump

A pump body assembly and a compressor are provided. The pump body includes: a spindle, wherein the spindle has a sliding vane chute, a back pressure oil cavity being at least a part of an oil passage is located at a tail end of the sliding vane chute, an oil outlet of the back pressure oil cavity is located at the top of the back pressure oil cavity, and a position of the oil inlet of the back pressure oil cavity is lower than that of an oil outlet of the back pressure oil cavity such that a lubrication medium enters the back pressure oil cavity through the oil inlet of the back pressure oil cavity and fills up the back pressure oil cavity and flows out from the top of the back pressure oil cavity.

Pump body assembly and compressor

The disclosure discloses a pump body and a compressor with the pump body. The pump body includes: a flange structure; a bearing, the bearing being provided with an inner ring and an outer ring, the inner ring being rotatably disposed on the flange structure, and an end face of the inner ring being abutted against a contact face of the flange structure; and an oil guide channel provided inside a side wall of the inner ring, or inside the flange structure, or the side wall of the inner ring and inside the flange structure, an outlet of the oil guide channel being positioned between the end face of the inner ring and the contact face of the flange structure, so as to introduce lubricating oil between the end face of the inner ring and the contact face of the flange structure.

The disclosure discloses a compressor pump body, a compressor and an air conditioner. The compressor pump body includes a sliding vane, a first flange and a second flange. The sliding vane includes a main body. The main body is provided with a first surface and a second surface which are arranged opposite to each other. The first surface abuts against the first flange, and the second surface abuts against the second flange. The first surface and/or the second surface are/is provided with an enlargement portion. An exhaust port is formed in the first flange and/or the second flange. When the sliding vane rotates to sweep the exhaust port, the enlargement portion can prevent two sides of the sliding vane in the rotation direction from communicating by means of the exhaust port.

Disclosed is a compressor including a cylinder, an upper flange and a lower flange respectively provided on an upper side and a lower side of the cylinder, and a main shaft having a sliding vane mounting portion. The sliding vane mounting portion of the main shaft is provided with at least two sliding vanes. Two rotary plates are provided. One rotary plate is provided between the sliding vane mounting portion and the upper flange, and another rotary plate is provided between the sliding vane mounting portion and the lower flange. Each of the rotary plates is fixedly connected with the main shaft and provided with exhaust openings in one-to-one correspondence with the exhaust sides of the sliding vanes and exhaust valves configured to control opening/closing of respective exhaust openings. The upper flange and the lower flange are both provided with exhaust passages corresponding to respective exhaust openings of each rotary plate.

Compressor with exhaust structure having multiple rotating plates each containing exhaust ports with corresponding exhaust valves

Disclosed are a sliding vane compressor and an exhaust structure thereof. The exhaust structure of the sliding vane compressor includes: an exhaust hole, the exhaust hole being formed in a flange of the sliding vane compressor and being in communication with a compression cavity of a cylinder of the sliding vane compressor; a guide channel, the guide channel being formed on the flange and penetrating through the flange; and an exhaust channel, the exhaust channel being formed on an eccentric circle of the sliding vane compressor, and the exhaust channel being used for communicating the compression cavity with the guide channel using the rotation of the eccentric circle. The sliding vane compressor and the exhaust structure thereof have a small exhaust loss, thereby effectively reducing the power consumption and the production and manufacturing costs of the sliding vane compressor.
