Abstract
The valve opens in response to a predetermined small pressure differential acting across the valve. As the pressure differential increases, the valve throttles the flow and when a high pressure differential exists the valve closes. The valve is designed to be placed in a by-pass circuit in an automotive air conditioning system to provide adequate flow under low cooling loads to cool and lubricate the compressor. Under normal and high evaporator loads, the by-pass flow is throttled or closed off completely to avoid needless consumption of energy.
