A variable capacity rotary compressor includes a housing having a cylindrical compressing chamber defined therein, a rotating shaft having an eccentric body part which rotates in the compressing chamber, a ring piston fitted over the eccentric body part of the rotating shaft so as to have the ring piston rotate while being in contact with an inner surface of the compressing chamber, a vane mounted in the housing so as to have the vane advance or retract in a radial direction of the compressing chamber in accordance with a rotation of the ring piston, and a control unit which is connected to the vane and moves in opposite directions in response to pressures of a refrigerant inlet and a refrigerant outlet of the compressor, so as to control a moving range of the vane. Accordingly, a simpler construction of the compressor is achieved and a refrigerant compressing capacity is easily controlled.

The unit of claim 1, wherein the at least one second portion of the applicator member comprises at least one groove in a lateral surface of the applicator member. 18. The unit of claim 17, wherein the at least one groove is formed over at least part of a periphery of the applicator member. 19. The unit of claim 17, wherein the at least one groove is oriented at least partially in a plane transverse to a longitudinal axis of the applicator member. 20. The unit of claim 19, wherein the plane is perpendicular to the longitudinal axis of the applicator member. 21. The unit of claim 19, wherein the plane is inclined with respect to the longitudinal axis of the applicator member. 22. The unit of claim 19, wherein the at least one groove has a cross-section transverse to the plane in which it is oriented, the cross-section comprising one of a C-shape, a U-shape with a square bottom, a U-shape with a rounded bottom, and a V-shape. 23. The unit of claim 17, wherein the at least one groove comprises a plurality of grooves. 24. The unit of claim 23, wherein, in the absence of force exerted on the application surface, the grooves have substantially the same axial height. 25. The unit of claim 23, wherein, in the absence of force exerted on the application surface, at least one of the grooves has a non-constant axial height. 26. The unit of claim 23, wherein, in the absence of force exerted on the application surface, the grooves are spaced apart substantial
