Three-unit assembly for pneumatic circuit

Abstract

A three-unit assembly for a pneumatic circuit includes a filter, a regulator and a lubricator, each having a body portion providing an air passageway therethrough. The air passageway of each terminates at respective inlet and outlet ports. Each of these engagement portions being provided adjacent to the inlet and outlet ports and including sloping engagement faces which come together in a somewhat V-shape, and face generally axially opposite the direction in which their respective inlet or outlet port opens. Coupling members are provided with passageways providing communication between the outlet port of one of the filter, regulator and lubricator and the inlet port of the next adjacent one of the filter, regulator and lubricator. Each of the coupling members including a pair of threaded bores which extend generally transversely to the coupling member's passageway. Pair-striding members for joining the coupling members and the filter, regulator and lubricator and including a center portion providing a passageway through which a bolt is inserted to engage a threaded opening provided on the coupling member. Each striding member including engagement faces which intersect each other in somewhat the same V-shaped orientation as the engaging faces on a respective filter, regulator or lubricator projection.
