Abstract
A compressor is disclosed generally comprising a cylinder block at least partially enclosing a compression chamber, a swash plate housing mounted adjacent the cylinder block, the swash plate housing at least partially enclosing a swash plate chamber, an inlet port in the swash plate housing, and a passageway connecting the swash plate chamber and compression chamber. In certain embodiments, the passageway comprises a fluid channel in the cylinder block. In some embodiments, at least one bearing is disposed in the swash plate chamber such that air entering through the inlet port flows over the bearing before flowing to the compression chamber.
Claims20
A compressor, comprising:
- a cylinder block at least partially defining a compression chamber;
- a swash plate housing mounted adjacent to said cylinder block, said swash plate housing at least partially defining a swash plate chamber;
- a fluid inlet port in said swash plate housing through which fluid enters the swash plate chamber without passing through any part of any cylinder block;
- a passageway by which the swash plate chamber is in fluid communication with the compression chamber, through which the fluid in the swash plate chamber flows to the compression chamber;
- at least one bearing positioned in the swash plate chamber such that fluid flows through said inlet port, into the swash plate chamber and over said bearing, through said passageway, and into the compression chamber;
- a swash plate disposed in the swash plate chamber, wherein said swash plate comprises:
- a rotatable inner part;
- and
- a non-rotatable outer part coupled to said inner part by at least one of said bearings.

A compressor comprising:
- a cylinder block at least partially defining a compression chamber;
- a swash plate housing mounted adjacent to said cylinder block, said swash plate housing at least partially defining a swash plate chamber;
- a fluid inlet port in said swash plate housing through when fluid enters the swash plate chamber without passing through any part of any cylinder block;
- a passageway by which the swash plate chamber is in fluid communication with the compression chamber, through which the fluid in the swash plate chamber flows to the compression chamber;
- at least one positioned in the swash plate chamber such that fluid flows through said inlet port, into the swash plate chamber and over said bearing, through said passageway, and into the compression chamber;
- a swash plate disposed in the swash plate chamber;
- and
- a gimbal arm coupled to said swash plate by at least one of said bearings.

5 more elements
A compressor, comprising:
- a cylinder block at least partially defining a compression chamber and having at least one piston channel therein;
- a swash plate housing mounted adjacent to said cylinder block, said swash plate housing at least partially defining a swash plate chamber;
- a fluid inlet port in said swash plate housing through which fluid enters the swash plate chamber without passing through any part of any cylinder block;
- a passageway by which the swash plate chamber is in fluid communication with the compression chamber, through which the fluid in the swash plate chamber flows to the compression chamber;
- a shaft disposed in said swash plate housing and cylinder block;
- a swash plate mounted on said shaft;
- at least one piston coupled to said swash plate and disposed in said at least one piston channel and slidable therein;
- and
- an actuator said swash plate, such that said actuator, in a first position, exerts a force on said swash plate appropriate to retain said swash plate in a position perpendicular to said drive shaft, such that said at least one piston remains idle, and, in a second position, exerts a force on said swash plate appropriate to pivot said swash plate, thereby causing reciprocal motion of said at least one piston.
