摘要： A refrigerant cycle is provided with a single three-way service valve that is utilized for draining and adding refrigerant. In the prior art, a second two-way valve was used in combination with the three-way valve. The present invention simply drains the refrigerant, and does not need to return the refrigerant. The present invention is particularly well suited for use with an environmentally benign refrigerant such as CO2.

摘要： An improvement to the oil supply grooves in connecting rods for compressors increases surface area in an upper bearing half. The upper bearing half transmits a force from a driveshaft to the connecting rod. The lower half of the connecting rod includes an oil supply groove that extends over the majority of a circumferential extent of a bearing surface in the lower half that contacts an eccentric. On the other hand, the inner surface of the upper half does not include any large oil supply groove such that the surface area between the upper half and the eccentric is maximized.
