Refrigeration compressor and system

A refrigeration compressor, comprising,

• a. a sealed housing,
• b. a cylinder block in the housing having an annular array of parallel axially disposed cylinders around a central axis,
• c. pistons reciprocable in the cylinders,
• d. a cam inclined relative to the axis of the cylinder block,
• e. means mounting the cam and the cylinder block for relative rotation to reciprocate the pistons in the cylinders,
• f. means providing an inlet chamber in the housing,
• g. intake valving for admitting low pressure fluid from the inlet chamber to the cylinders on the intake strokes of the pistons,
• h. an outlet chamber in the housing at the end of the cylinder block opposite from the cam,
• i. outlet ports leading axially respectively from the cylinders to the outlet chamber,
• j. leaf valves associated with the outlet ports for discharging high pressure fluid from the cylinders to the outlet on the compression strokes of the pistons, and
• k. a circular dish-shaped baffle having a central portion in spaced relation to the cylinder block and an outer periphery overlying and contiguous with the leaf valves and defining restricted passages between the leaf valves from the interior of the baffle to the outlet.

A refrigeration compressor, comprising,

• a. a sealed housing,
• b. a stationary cylinder block in the housing having an annular array of parallel axially disposed cylinders around a central axis,
• c. pistons reciprocable in the cylinders,
• d. a rotatable cam having a cam surface inclined relative to the axis of the cylinder block,
• e. bearing means on the pistons engageable with the cam surface,
• f. means for holding the bearing means on the inclined cam surface,
• g. means providing an inlet chamber in the housing,
• h. intake valving for admitting low pressure fluid from the inlet chamber to the cylinders on the intake strokes of the pistons,
• i. an end cover on the housing forming an outlet chamber at the end of the cylinder block opposite from the cam,
• j. an outlet in the end cover leading from the outlet chamber,
• k. an annular array of outlet ports in the cylinder block leading axially respectively from the cylinders to the outlet chamber,
• l. leaf valves associated with the outlet ports for discharging high pressure fluid from the cylinders to the outlet chamber on the compression strokes of the pistons, and
• m. a circular dish-shaped baffle having a central portion secured in spaced relation to the cylinder block and an outer periphery overlying and contiguous with the leaf valves and defining restricted passages between the leaf valves from the interior of the baffle to the outlet chamber.
