Air conditioner compressor

Claim 2

A compressor assembly for compressible fluids comprising a housing, a cylinder body located in one end of said housing, multiple cylinders in said cylinder body, each cylinder receiving a working piston, a driveshaft journalled in said housing, a drive pulley journalled on said housing, fluid pressure operated clutch means for connecting drivably one end of said driveshaft to said pulley, an inlet port and an outlet port formed in said cylinder body adjacent each axial end of each cylinder, valve reeds registering with each port whereby fluid is admitted to one side of said working piston as fluid is pumped by said piston through the outlet port at the opposite end of said cylinder, a piston rod extending axially from each piston in the direction of said driveshaft, a swash plate driving connection between said driveshaft and said piston rods comprising a swash plate fixed to said drive-shaft, an articulated crosshead surrounding said swash plate, said swash plate comprising multiple segments, each having a radially outwardly facing bearing surface and a pair of radially extending walls situated on opposite sides of the margin of said swash plate, one wall being connected to a separate one of said piston rods and a thrust bearing slidably engaging the surfaces of said swash plate and transmitting thrust forces through said crosshead to said piston rods in each axial direction upon rotation of said driveshaft, the radially outward components of the forces applied by said swash plate being transmitted through the respective bearing surfaces of said crosshead segments to the surrounding housing, the outlet ports for each working cylinder at each end thereof comprising a pair of valve openings extending radially through said cylinder body and the inlet ports thereof extending axially, each of the inlet ports being in fluid communication and each of the outlet ports being in fluid communication.

Claim 3

A compressor assembly for compressible fluids comprising a housing, a cylinder body located in one end of said housing, multiple cylinders in said cylinder body, each cylinder receiving a working piston, a driveshaft journalled in said housing, a drive pulley journalled on said housing, fluid pressure operated clutch means for connecting drivably one end of said driveshaft to said pulley, an inlet port and an outlet port formed in said cylinder body adjacent each axial end of each cylinder, valve reeds registering with each port whereby fluid is admitted to one side of said working piston as fluid is pumped by said piston thRough the outlet port at the opposite end of said cylinder, a piston rod extending axially from each piston in the direction of said driveshaft, a swash plate driving connection between said driveshaft and said piston rods comprising a swash plate fixed to said driveshaft, an articulated crosshead surrounding said swash plate, said swash plate comprising multiple segments, each having a radially outwardly facing bearing surface and a pair of radially extending walls situated on opposite sides of the margin of said swash plate, one wall being connected to a separate one of said piston rods and a thrust bearing slidably engaging the surfaces of said swash plate and transmitting thrust forces through said crosshead to said piston rods in each axial direction upon rotation of said driveshaft, the radially outward components of the forces applied by said swash plate being transmitted through the respective bearing surfaces of said crosshead segments to the surrounding housing, bearing means for journalling said driveshaft at spaced locations in said housing, lubrication oil passages located in part in said driveshaft and extending to said swash plate assembly and bearings for said driveshaft, conduit structure extending from the high pressure side of said pump to said bearing passages and to said clutch means, valve means situated in and partly defining a portion of said conduit structure extending to said clutch means whereby actuating pressure is distributed to and exhausted from said clutch means thereby effecting a selective connection between said drive pulley and said driveshaft, the outlet ports for each working cylinder at each end thereof comprising a pair of valve openings extending radially through said cylinder body and the inlet ports thereof extending axially, each of the inlet ports being in fluid communication and each of the outlet ports being in fluid communication.

Claim 4

A compressor assembly for compressible fluids comprising a housing, a cylinder body located in one end of said housing, multiple cylinders in said cylinder body, each cylinder receiving a working piston, a driveshaft journalled in said housing, a drive pulley journalled on said housing, fluid pressure operated clutch means for connecting drivably one end of said driveshaft to said pulley, an inlet port and an outlet port formed in said cylinder body adjacent each axial end of each cylinder, valve reeds registering with each port whereby fluid is admitted to one side of said working piston as fluid is pumped by said piston thRough the outlet port at the opposite end of said cylinder, a piston rod extending axially from each piston in the direction of said driveshaft, a swash plate driving connection between said driveshaft and said piston rods comprising a swash plate fixed to said driveshaft, an articulated crosshead surrounding said swash plate, said swash plate comprising multiple segments, each having a radially outwardly facing bearing surface and a pair of radially extending walls situated on opposite sides of the margin of said swash plate, one wall being connected to a separate one of said piston rods and a thrust bearing slidably engaging the surfaces of said swash plate and transmitting thrust forces through said crosshead to said piston rods in each axial direction upon rotation of said driveshaft, the radially outward components of the forces applied by said swash plate being transmitted through the respective bearing surfaces of said crosshead segments to the surrounding housing, bearing means for journalling said driveshaft at spaced locations in said housing, lubrication oil passages located in part in said driveshaft and extending to said swash plate assembly and bearings for said driveshaft, conduit structure extending from the high pressure side of said pump to said bearing passages and to said clutch means, valve means situated in and partly defining a portion of said conduit structure extending to said clutch means whereby actuating pressure is distributed to and exhausted from said clutch means thereby effecting a selective connection between said drive pulley and said driveshaft, the outlet ports for each working cylinder at each end thereof comprising a pair of valve openings extending radially through said cylinder body and the inlet ports thereof extending axially, each of the inlet ports being in fluid communication and each of the outlet ports being in fluid communication.
