US 11,920,593 B2 · Compressor stop valve and associated system

Abstract

A compressor system is provided that includes a contact cooled compressor and a coolant separator. The coolant separator is used to remove coolant fluid from a compressed flow stream produced by the contact cooled compressor during its operation. The coolant separator routes the removed coolant fluid back to the contact cooled compressor for further use. In some forms the coolant fluid is cooled prior to delivery back to the compressor. A stop valve can be provided in the coolant fluid return line to halt the flow of the fluid. A pressure sensitive member can be disposed to sense pressure of the coolant fluid that has been routed past the stop valve. Operation of the compressor can be changed as a result of the sensed pressure from the pressure sensitive member. Information from a temperature sensitive member can also be used to change operation of the compressor.

Dependent claims

A compressor assembly comprising:

a compressor configured to raise a pressure of a compressible fluid, the compressor configured to employ oil within the compressor to lubricate at least one compressor elements;
an oil reservoir coupled with the compressor via a conduit, the conduit configured to convey oil under pressure to the compressor from the oil reservoir;
a controller configured to control operation of the compressor;
and
a temperature sensor in thermal communication with oil conveyed by the conduit to determine a temperature of the oil, the temperature determined by the temperature sensor being biased to provide an estimated temperature,
wherein the controller is configured to cause operation of the compressor to halt when the controller determines that the estimated temperature exceeds an operational threshold temperature.
