Abstract
A compressor includes a cylinder block having a first bore and a cylinder head overlapping the cylinder block. The cylinder head has a second bore aligned with the first bore. The second bore is separated into a plurality of distinct regions including a suction region and an economizer region. A plurality of valves includes a suction valve selectively operable to fluidly couple the suction region and the first bore, and an economizer valve selectively operable to fluidly couple the economizer region and the first bore.
Claims6
A compressor comprising:
- a cylinder block having a first bore;
- a cylinder head overlapping the cylinder block, the cylinder head having a second bore aligned with the first bore, wherein the second bore is separated into a plurality of regions including a suction region and an economizer region, the economizer region being distinct from the suction region;
- a plurality of valves including a suction valve selectively operable to fluidly couple the suction region and the first bore, and an economizer valve selectively operable to fluidly couple the economizer region and the first bore;
- a sensor operable to monitor a pressure within the first bore, wherein the economizer valve is operable based on a rate of change of a pressure within the first bore measured and;
- a controller operably coupled to the sensor and to the economizer valve, wherein the controller is configured to operate the economizer valve in response to the rate of change of the pressure sensed within the first bore.
