    Abstract: A piston type compressor includes a housing, which defines a crank chamber. A valve plate forms a part of the housing. A drive shaft is located in the crank chamber. A contact member is plastically deformed and press fitted to the drive shaft. An inner wall and a first sub-plate are located in the housing and limit the axial movement of the drive shaft, respectively. After the contact member is attached to the drive shaft, the axial load required to change the position of the contact member is greater than the maximum axial load applied to the drive shaft due to the increase of the pressure in the crank chamber, and less than the load applied to the contact member by the first sub-plate in accordance with the difference in the thermal expansion coefficient of the housing and the drive shaft.

    Abstract: A control apparatus that promptly increases the displacement of a compressor after the compressor is started while liquefied refrigerant is lingering in an external circuit. The control apparatus includes a restricting passage. The restricting passage is located in a first pressure introduction passage, through which the pressure of the first pressure monitoring point flows to the control valve. The restricting passage decreases the pressure of refrigerant that flows through the passage. When the compressor is started while liquefied refrigerant is lingering in the external circuit and the pressure of the first pressure monitoring point is abruptly increased, the restricting passage reduces the increase of the pressure that is detected by the control valve. Therefore, the displacement of the compressor is promptly increased.

    Abstract: An accurate and low cost sensing apparatus for a swash or wobble plate compressor that requires no modifications in compressor design or operation, and which provides a repeatable and accurate measure of compressor speed and stroke. The apparatus includes a sensor module and a stroke sensing circuit. The compressor has an outer housing formed of aluminum or other non-magnetic material, as is customary in automotive air conditioning systems. The sensor module includes a magnetic field responsive sensor such as a Hall Effect or magneto-resistive (MR) sensor, and is attached to the periphery of the housing in proximity to a reciprocating ferrous element such as a bushing shoe on the swash or wobble plate assembly. The sensor produces a quasi-sinusoidal output voltage signal having a frequency proportional to compressor speed, and the stroke sensing circuit determines the compressor stroke by band-pass filtering, amplifying, and peak detecting the signal. The output of the stroke sensing circuit is substantially insensitive to noise, and the relationship between it and the compressor stroke is substantially linear, resulting in a reliable, accurate and inexpensive sensing apparatus.

    Abstract: A variable displacement compressor having a pressurizing passage, which extends through a cylinder block. The pressurizing passage connects a discharge chamber and a crank chamber. A valve is arranged in the pressurizing passage. A drive shaft rotates and produces centrifugal force that causes the valve to open the pressurizing passage. The pressure of the crank chamber is increased when the rotation of the drive shaft is accelerated thereby opening the pressurizing passage with the valve. This moves a swash plate such that its inclination, relative to a plane perpendicular to the drive shaft, decreases. As a result, the compressor shifts from a maximum displacement state to a minimum displacement state, which improves the acceleration performance of an engine connected to the compressor. Furthermore, the displacement of the compressor in the minimum displacement state is 50% of that in the maximum displacement state. This prevents an excessive decrease in the cooling capability of the compressor.
