20090205347 | Variable Displacement Compressor With A Compensated Suction Shufoff Valve - A variable displacement compressor with a compensated suction shutoff valve (SSV). The SSV prevents noise generated by a suction reed valve at low refrigerant flow rates in an internal suction region from propagating to an air conditioner evaporator by moving a piston to obstruct an opening and restrict fluid communication. The degree of restriction is decreased by an opening force generated by refrigerant at an external suction pressure acting over a first area, and increased by refrigerant at a crankcase pressure acting over a second area. The second area is smaller than the first area so that at high refrigerant flow rates, the effect of crankcase pressure is reduced so that the restriction is reduced and the compressor operates at greater efficiency. The piston position is also influenced by refrigerant at a pressure intermediate the external suction pressure and the internal suction pressure acting over a third area. | 08-20-2009 |
20090311109 | Variable Displacement Compressor With A Discharge Pressure Compensated Suction Shutoff Valve - A variable displacement compressor with a discharge pressure compensated suction shutoff valve (SSV). The SSV prevents noise generated at low refrigerant flow rates by a suction valve from propagating out of the compressor and to an air conditioner evaporator by variably restricting a fluid communication with the suction valve. The SSV is configured so the variable restriction is increased correspondingly with the discharge pressure if the discharge pressure is less than a threshold that is an indicator of low refrigerant flow rates, and the restriction is decreased if the discharge pressure is greater than the threshold. | 12-17-2009 |

The modulating valve includes a valve disk for covering a valve aperture, a bellows in sealed engagement with the egress end of a valve body, and a valve stem connecting the valve disk and the bellows. A bellows spring is disposed in the bellows for biasing the valve disk to open the valve aperture. When the pressure in the suction chamber decreases below a predetermined pressure, the bellows spring moves the bellows and the valve disk to open the valve aperture and increase fluid flow from the compression chamber to the bellows chamber to subsequently allow the valve piston to uncover the holes of the valve body and increase fluid flow through the suction shutoff valve to the suction chamber. | 06-10-2010 |
