Abstract
Oil management apparatus for a refrigeration chiller includes a housing mounted to the head wall of an oil supply tank. The housing defines a series of ports and internal flow passages in communication with a valve cavity. A valve spindle disposed in the cavity is configured and positionable such that a plurality of oil flow passages within the chiller are capable of being setup in order to accommodate various chiller lubrication needs including those as they relate to both chiller operation and maintenance. The combination of an integral housing and single valve eliminates a large number of individual valves and the need to connect those valves and various chiller lubrication components, such as an oil filter and oil pressure regulator, with individual sections of difficult to fabricate piping. As a result, the likelihood of error in the setup of a chiller lubrication system is significantly reduced.
