Slant plate type compressor
First Claim
1. In a slant plate type compressor including a drive mechanism coupled to and reciprocating a plurality of pistons, said drive mechanism including a drive shaft and coupling means for coupling said drive shaft to said pistons, said coupling means including a slant plate disposed about said drive shaft and being rotatable with said drive shaft, a wobble plate disposed about a boss of said slant plant, an annular balance weight being disposed about and coupled to said boss of said slant plate so that said wobble plate is disposed between said slant plate and said annular balance weight, said rotary motion of said drive shaft and slant plate causing said wobble plate to nutate and thereby reciprocating said pistons, the improvement comprising:
- resilient biasing means for substantially eliminating a gap between said wobble plate and said annular balance weight.

Abstract
A slant plate type compressor is disclosed. The drive mechanism of the compressor is provided with a mechanism which substantially eliminates a gap between the wobble plate and the balance weight ring on the slant plate, thereby preventing an offensive noise caused by the collision between the wobble plate and the balance weight ring during operation of the compressor.

6. In a slant plate type compressor including a drive mechanism coupled to and reciprocating a plurality of pistons, said drive mechanism including a drive shaft and coupling means for coupling said drive shaft to said pistons, said coupling means including a slant plate disposed about said drive shaft and being rotatable with said drive shaft, a wobble plate disposed about a boss of aid slant plate, an annular balance weight being disposed about and coupled to said boss of said slant plate so that said wobble plate is disposed between said slant plate and said annular balance weight, said rotary motion of said drive shaft and slant plate causing said wobble plate to nutate and thereby reciprocating said pistons, the improvement comprising:
-
biasing means for substantially eliminating a gap between said wobble plate and said annular balance weight; wherein said annular balance weight comprises an annular recess and said boss of said slant plate comprises an annular groove; and wherein said biasing means further comprises; a first annular member disposed in both said groove and said recessed portion; and a second annular member of an elastic material disposed in said annular recessed portion and between said first annular member and said boss so as to continuously urge said annular balance weight toward said wobble plate.

- 7. A refrigerant compressor having a slant plate coupled to a wobble plate, said slant plate being further rotatively actuated by a rotating drive shaft, said rotating motion of aid slant plate being translated into a wobbling motion of said wobble plate and thereby causing a reciprocating motion of at least one piston, said slant plate being further coupled to a balance ring, said wobble plate being disposed between said balance ring and said slant plate, the refrigerant compressor further comprising resilient biasing means for biasing said wobble plate toward said balance ring to substantially eliminate any gap between said wobble plate and said balance ring.

11. A refrigerant compressor having a slant plate coupled to a wobble plate, said slant being further rotatively actuated by a rotating drive shaft, said rotating motion of said slant plate translated into a wobbling motion of said wobble plate and thereby causing a reciprocating motion of at least one piston, said slant plate being further coupled to a balance ring, aid wobble plate being disposed between said balance ring and said slant plate, the refrigerant compressor further comprising means for biasing said wobble plate toward said balance ring to substantially eliminate any gap between said wobble plate and said balance ring, wherein said balance ring is coupled to a boss of said slant plate, and said biasing means includes an annular member fixedly coupled to said boss of said slant plate and an annular resilient member is disposed between said fixed annular member and said balance ring.
