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.

A vane motor with a rotor body driven by compressed air having vane gaps for radially movable vanes and a rotor shaft for rotatably bearing the rotor body relative to a motor bushing. A method for lubricating a vane motor that ensures particularly long, low-service operation is provided. The rotor shaft is configured as a hollow shaft with a first lubricant reservoir in the interior. The first lubricant reservoir has a lubricant filling opening accessible from the outside of the vane motor. The first lubricant reservoir is connected by at least one radial lubricant hole to at least one further lubricant reservoir arranged in a section of the rotor body between two vane gaps, and/or is connected to an outlet opening arranged in one of the vane gaps for supplying lubricant into the vane gap.

A metal film includes portions that are opposed to each other and located away from each other between the first winding and the second winding. The metal film includes the first linear part that is thermally coupled to a housing. The average value of electric resistance per unit length in the peripheral direction of the first linear part of the metal film is greater than an average value of electric resistance per unit length of locations other than the first linear part.

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.

A rotary compressor may include a case, a cylinder, a roller, a vane, a main bearing and a sub bearing, and a discharge passage defined in the main bearing or the sub bearing to discharge refrigerant compressed in a compression space. The discharge passage may include at least one discharge hole formed through the main bearing or the sub bearing, and at least one discharge guide groove having a first end that communicates with the at least one discharge hole and a second end that extends from the at least one discharge hole toward a contact point between the cylinder and the roller and is recessed from one surface of the main bearing or the sub bearing forming the compression space. Accordingly, an amount of refrigerant remaining in the compression space even after a discharge stroke may be reduced.

A rotary compressor is provided that may include a rotational shaft including at least one protrusion formed on an outer peripheral surface, first and second bearings configured to support the rotational shaft in a radial direction, a cylinder disposed between the first and second bearings to form a compression space, a rotor disposed in the compression space and coupled to the rotational shaft to compress a refrigerant as the rotor rotates, and at least one vane slidably inserted into the rotor, the at least one vane coming into contact with an inner peripheral surface of the cylinder to separate the compression space into a plurality of regions. The rotor may include at least one groove which is formed on an inner peripheral surface and faces the at least one protrusion.

The rotor may include at least one groove which is formed on an inner peripheral surface and faces the at least one protrusion.

A vane-type compressor is provided. The vane-type compressor may include a cylindrical cylinder having opposite open ends along an axial direction, an inner circumferential surface of the cylinder being eccentric from an outer circumferential surface of the cylinder, a main bearing and a sub bearing, respectively, positioned at the open ends of the cylinder, a rotor coupled to a shaft supported by the main bearing and the sub bearing and installed eccentric from the inner circumferential surface of the cylinder, and a plurality of vanes coupled to the rotor to rotate along with the rotor, the plurality of vanes dividing the inner circumferential surface of the cylinder into a plurality of spaces including a suction chamber and a compression chamber when the rotor rotates. An elastic member may be installed at a point at which a minimum gap is maintained between the inner circumferential surface of the cylinder and the rotor so that a portion of the elastic member protrudes inward of the inner circumferential surface of the cylinder. An end of a discharge dimple formed in the inner circumferential surface of the cylinder extends up to the point.
