A gas compressor includes a housing defining a compression chamber, a crankshaft having an eccentric surface radially offset from the axis of rotation of the crankshaft, an orbiting ring rotatably mounted on the eccentric for rotation about an axis offset from the shaft axis, a cylindrical post coaxial with the axis of the housing passages for carrying gas to and from the compression chamber, vanes movable radially with respect to the orbiting ring, and pressure sensitive valves that open exhaust passages from the compression chamber. The orbiting ring rotates in continual contact with the inner surface of the housing and the outer surface of the cylindrical post. Compression occurs within a first stage space and a second stage space, each space divided into compression chambers by the sliding vanes and contact between the ring and post or between the ring and housing. An intermediate pressure chamber is located in one end of the housing and this chamber can be configured to allow for intercooling of the refrigerant. It is also possible to provide gas separation of the discharge gas and return the separated gas to the intermediate chamber for improved efficiency of the compressor.

An accumulator for use in an air conditioning system for an automotive vehicle includes a refrigerant processing cartridge with an outer casing, a desiccant, a filter, a separator, and a regulator for controlling the pressure of the refrigerant within the air conditioning system.

Automotive air conditioning system accumulator with refrigerant

An accumulator for use in an air conditioning system for an automotive vehicle includes a cylindrical housing with an inlet tube and an outlet tube extending through the housing, and an axially insertable refrigerant processing cartridge positioned within the housing and including an outer casing, a desiccant, a filter and a separator, all for processing the refrigerant flowing through the accumulator.

Accumulator with refrigerant processing cartridge for automotive air

An accumulator for an air conditioning system having a compressor, a condenser and an evaporator wherein the accumulator receives refrigerant from the evaporator at a location near an upper wall thereof, said accumulator including a domed baffle plate in its interior adjacent the accumulator inlet opening whereby liquid portions of the refrigerant are dispersed to the sides of the accumulator allowing the gaseous components of the refrigerant to accumulate in the upper regions of the accumulator adjacent the inlet opening of an outlet tube that extends vertically through the accumulator.

Domed accumulator for automotive air conditioning system

A compressor protector system is an air conditioning system that includes a compressor driven by an engine through an electromagnetic clutch. If the refrigerant charge is below the level necessary for proper compressor cooling and lubrication a pressure or temperature responsive switch cycles at an excessive rate. A digital counter adds the number of cycles occuring over a given time, compares the rate of switch pulses to a predetermined maximum and operates to disengage the clutch and signal the vehicle operator that corrective action to restore the refrigerant charge is required.
