摘要： A compressor includes a male rotor (26) having a screw-type boy portion (30) extending from a first end (31) to a second end (32) and held within a housing assembly for rotation about a first rotor axis (500). A female rotor (27, 28) has a screw-type female body portion (33, 34) meshed with the male body portion and extending from a first end (35, 36) to a second end (37, 38) and held within the housing assembly for rotation about a second rotor axis (501, 502). An end seal (120) has a first surface (126) engaging the female body portion first end and being asymmetric around the second axis.

摘要： Provision is made for stacking one condenser on another by mounting apparatus which includes a channel for receiving and supporting the existing feet at the base of the upper unit, and a clip member for securing the combination to the lower edge of the lower unit cover. Where the upper and lower units are the same size, a single fastener attaches both the feet and the clip to the channel. Where the upper unit is smaller than the lower unit, separate fasteners are applied to secure the feet to the channel and to secure the channel to the clip.

摘要： An unbiased valve is located within a muffler. The valve is positioned by the pressure differential across the valve and is either in the full open or full closed position. A pressure equalization tube is provided between the downstream cavity of the muffler and the back of the valve such that flow pattern produced low pressure areas are avoided and the valve can react to actual pressure differentials in the flow.
