ABSTRACT:
A scroll-type compressor includes a front housing, a rear housing, and stationary and movable scrolls engaging with each other to define a plurality of compression chambers therebetween. The stationary scroll is connected to the rear housing to define a discharge chamber therebetween. The stationary and movable scrolls are provided between the front and rear housings so that the movable scroll moves along an orbiting path. A drive shaft extends through the front housing and is drivingly connected to the movable scroll. The rotation of the drive shaft moves the movable scroll along the orbiting path to shift the compression chambers from the periphery to the center of the scrolls with the volume of the chambers reducing. A slider plate, substantially in the form of a ring, for providing a sliding surface for the movable scroll, relative to the front housing, is disposed between the front housing and the movable scroll. The slider plate includes first and second slots which are disposed diametrically opposite to each other and extend radially and circumferentially, respectively. A pair of pins are provided for engagement with the first and second slots of the slider plate to lock and secure the slider plate to the front housing or to the movable scroll.
