Abstract: A distributor for feeding the liquid-vapor mixture of refrigerant from the expansion valve to the core elements of an evaporator of an air conditioning system to provide equal distribution of both the liquid and vapor components. The distributor involves either a single header with separate orifices for the liquid and vapor in each core element or a pair of distribution headers to carry the separated component phases from a separator with an orifice for each phase in each core element where the phases would be recombined to pass through the core elements to a common outlet.

Abstract: Separation of lubricating oil, entrained in the discharge gas produced by a rotary vane compressor, is achieved in a relatively small space by initially passing the oil-laden discharge gas through a first closed chamber, containing an oil separating element, to form a stream of gas having some of its oil removed and having a desired velocity uniformly distributed across the stream's cross section. The gas stream is then circulated within a second and larger closed chamber where the remaining oil is separated out by gravity settling and impingement on the second chamber's walls. The separated oil collects in a reservoir at the bottom of the second chamber to form an oil pool. The oil-free discharge gas exits through an outlet in the second chamber.
