Abstract

A device for purging contaminated oil from a lubrication conduit is provided. The device may be used wherever a contaminated fluid or gas is purged from a conduit circuit. The preferred embodiment includes a housing which may be finned to allow the radiating of heat from engine oil to the environment. The housing includes an inlet and a primary and secondary outlet adapted for serial installation in a conduit. The housing is further provided with primary bore and a secondary bore therethrough so as to allow communication between the inlet and the primary and secondary outlets. The primary bore includes a check valve seat with in the housing. The secondary outlet is fitted with a diverter valve seat and a diverter valve to allow a user to selectively open and close the diverter valve. The check valve allows normal oil flow during engine operation when the diverter valve is shut off but closes when a negative pressure exists at the primary outlet with respect to the secondary outlet.

Claims

1. A device for purging fluid from a source, comprising;

a. a housing having a primary bore and a secondary bore, said primary bore terminating in a first outlet, said secondary bore terminating in a second outlet, and an inlet communicating with said first and second outlets;

b. control means for selectively diverting the flow of fluid between said first and second outlets, said control means comprising a check valve seat located in said primary bore, a check valve face received by said check valve seat, and spring means exerting a spring force of a certain valve to urge said valve face into reception by said valve seat to close said first bore to fluid flow until said spring force is overcome by a fluid force on said check valve face, said control means further comprising a diverter valve seat located in said secondary bore, a diverter valve face received by said diverter valve seat and means to vary the distance between said diverter valve face and said diverter valve seat to divert the flow of fluid through said inlet from said primary bore and first outlet, to said secondary bore and said second outlet.

2. The device of claim 1 in which said means for varying the distance between said diverter valve seat and said diverter valve face comprises a manually operated member.

3. The device of claim 2 in which said manually operated member includes a threaded portion on said member which threadingly engages a threaded portion on said secondary bore.

4. The device of claim 1 which further comprises a finned surface on said housing.
