Abstract

A flow selector device whose fluid flow is regulated by the rotational setting of a rotor body in a housing; and a split retainer form of an abutment, releasably held between opposed abutments of the rotor body and the housing body, serves to restrain the rotor body against movement axially of the housing as otherwise would be urged by the axial force result of the actuation of a spring pressed rotor-indexing detent feature and of a sealing feature, both of which are carried by the housing and have an effect of pushing the rotor body axially of the housing due to their compressive nature.
