Abstract
A scroll compressor has a fixed scroll and an orbiting scroll nested with one another within a shell. A hub extends axially from a lower surface of the orbiting scroll with a central bore formed therein. A crankshaft, having an eccentric pin extending axially from one end thereof, is drivable by a motor. A passageway for the delivery of a lubricant extends through the crankshaft and the eccentric pin. A slider block is received by the central bore, and a pin bore, which extends axially through the slider block, receives the eccentric pin. An axially extending projection maintains a gap between the slider block and the orbiting scroll which enhances the flow of lubricant to bearing surfaces of the scroll compressor.
Claims3
A scroll compressor comprising:
- a first scroll member having a generally spiral wrap;
- a second scroll member having a generally spiral wrap fitting within said spiral wrap of said first scroll member, and having a bore with an end surface;
- a motor for driving said second scroll member to orbit relative to said first scroll member;
- a crankshaft having an eccentric pin extending axially from one end, and being rotatably driveable by said motor;
- a slider block received within said second scroll bore, said slider block having a pin bore for receiving said eccentric pin, and an end surface facing said end surface of said second scroll member;
- and
- a projection extending axially from one end of said slider block, and maintaining a gap between said end surface of said slider block, and said end surface of said orbiting scroll bore.
