Publication number: 20100095690Abstract: A compressor has a housing. A crank is carried by the housing for rotation about a crank axis. A cylinder is defined within the housing and has a proximal portion and a distal portion. The distal portion is smaller in transverse cross-sectional area than is the proximal portion. A piston is held within the housing for reciprocal movement at least partially within the cylinder. The piston also has a distal portion smaller in transverse cross-sectional area than a proximal portion. A connecting rod is pivotally coupled to the crank for relative rotation about a proximal axis and to the piston for relative rotation about a distal axis. A first compression chamber exists in the cylinder distal portion beyond the end of the piston. A second compression chamber exists in the cylinder proximal portion beyond a piston shoulder. The first and second compression chambers are non-series and non-parallel.Type: ApplicationFiled: December 31, 2006Publication date: April 22, 2010Applicant: CARRIER CORPORATIONInventors: James W.

Publication number: 20080282718Abstract: A vapor compression system includes a variable speed single stage compressor, a heat rejecting heat exchanger, an expansion device, and a heat accepting heat exchanger. The speed of the compressor is varied to control the refrigerant flow rate and match the cooling load requirements of the vapor compression system. A temperature sensor measures an air temperature in the refrigerated container. When the temperature sensor detects that the air temperature is above a threshold temperature, the microcontroller increases the speed of the compressor to increase the refrigerant flow rate and the cooling capacity of the vapor compression system. When the air temperature sensor detects that the air temperature is within a predetermined range from the set point temperature, the microcontroller sends a signal to slightly decrease the speed of the compressor, allowing fine adjustment of the cooling capacity of the vapor compression system to prevent overcooling of the refrigerated container.Type: ApplicationFiled: December 1, 2005Publication date: November 20, 2008Inventor: Wayne P.

Patent number: 6565336Abstract: In its unstressed state, a suction valve is spaced from its valve seat such that the suction valve must be deformed against its inherent spring force in order to achieve seating. The spring force due to deformation provides an opening bias to the suction valve such that it opens earlier in the suction stroke and offsets the effects of adhesion due to the presence of oil between the seating surface and the valve.Type: GrantFiled: May 6, 1998Date of Patent: May 20, 2003Assignee: Carrier CorporationInventors: Bruce A. Fraser, Wayne P. Beagle, Peter F. Kaido
