Abstract: A refrigeration unit having a compressor that includes a cast member, a cavity formed in the cast member, and an oil filter element dividing the cavity into an inlet cavity and an outlet cavity. An inlet port for directing the unfiltered oil into the inlet cavity and an outlet port for directing filtered oil out of the outlet cavity are also included. The filter element is secured in the cavity between an integral plate on one end and ears on the opposite end. A seal between the cast member and the removable cover is included. Also included is another seal positioned between the inlet and outlet cavities. The filter element may be cylindrical. At least one isolation valve that prevents or allows flow into and out of the filter cavity may be included. The inlet port may be formed in the cast member and the outlet port may be formed in the removable cover, or vice versa. At least one lubrication point and an oil conduit communicating between the lubrication port and the outlet port are included.

Abstract: A suspension system for a component of an air conditioning system adapted for mounting the air conditioning system to a support surface. The suspension system is designed for use with an air conditioning system component that is mounted on spaced apart support rails. The suspension system is integrated into the support rail and eliminates the need for a self contained suspension system that must have specially designed mounting points for attachment to the support rails. The integrated design provides for resistance to lateral loads and facilitates the interchange and replacement of suspension system components. The suspension system comprises a spring for absorbing motion occurring between the air conditioning system component and the support surface. The spring has a first end and a second end, and defines a spring axis extending between the two ends. A receptacle is formed integral to a respective one of the support rails for supporting the first end of the spring.
