L1 represents a distance from an intersecting point located on one end side where the first outer surface and the second outer surface intersect each other to the rotation center, L2 represents a distance from an intersecting point located on an other end side where the first outer surface and the second outer surface intersect each other, to the rotation center, and L3 represents a distance from the third outer surface to the rotation center, a relationship of L1>L3≥L2 is satisfied.

An accumulator for a compressor and a compressor having an accumulator are disclosed. The accumulator may include a case configured to be disposed at an outside of a shell of a compressor and defining a refrigerant accommodating space, a refrigerant connection pipe having a first end that communicates with an outlet side of an evaporator and a second end that communicates with the refrigerant accommodating space of the case, and a refrigerant suction pipe having a first end that communicates with the refrigerant accommodating space of the case and a second end that communicates with a suction side of the compressor. The refrigerant suction pipe may be fixed to a lower surface and an upper surface of the case defining the refrigerant accommodating space. Therefore, the refrigerant suction pipe may be fixed to the case of the accumulator without a separate pipe holder, thereby attenuating vibration of the accumulator and reducing manufacturing costs.

The compressor housing (10) and an accumulator container (26) of the accumulator are made of a metal material. The mounting member (50) is at least partially made of a resin material and has a first joint portion (J1), which is joined to an outer peripheral surface (10a) of the compressor housing (10).

A scroll compressor is provided that may include a casing having an oil storage space, a suction pipe and a discharge pipe being connected to the casing, a drive motor installed in an inner space of the casing and including a rotational shaft rotated by a generated drive force, a compression unit installed in the inner space of the casing and having a compression chamber operated by the drive motor to compress a refrigerant, an oil separator coupled to the discharge pipe, that receives refrigerant discharged after being compressed by the compression unit, separates oil from the refringent, and supplies the oil to an inside of the casing, and a subframe that rotatably supports the rotational shaft at one side of the rotational shaft. The subframe may be provided with an oil recovery flow path that extends in a radial direction and guides oil to be recovered toward the inside of the casing from the oil separator.

A compressor includes: an annular cylinder; a rotation shaft which is rotated by the motor; a piston which revolves along an inner circumferential surface of the cylinder, and forms a cylinder chamber on the inside of the cylinder; a vane which protrudes to the inside of the cylinder chamber from a vane groove provided in the cylinder, and divides the cylinder chamber into an inlet chamber and a compression chamber by abutting against the piston; and an injection hole which injects a liquid refrigerant to the inside of the compression chamber. The center of the injection hole is disposed to be within a fan-like range of which a center angle is equal to or less than 40° toward a side opposite to a connection position between the compressor housing and the inlet unit from a center line of the vane groove in the circumferential direction of the rotation shaft.

The present disclosure relates to an air conditioner and a compressor. The compressor includes: a first cylinder assembly, including a first cylinder body and a first sliding vane, a volume control assembly, including a pressure regulator; wherein the pressure regulator is provided with a storage cavity, and the storage cavity is communicated with the variable volume control cavity; wherein the first sliding vane is configured to slide in a reciprocating manner between the first compression cavity and the variable volume control cavity along the first sliding vane groove, to change the volume of the variable volume control cavity; and the refrigerant introduced into the variable volume control cavity flows between the variable volume control cavity and the storage cavity along with a change of the volume of the variable volume control cavity.
