Directional flow control device

Abstract:

A directional flow control device includes a housing extending along a longitudinal axis between an inlet end and a discharge end. A flow deflector is received in the housing. The flow deflector is rotatable in the housing about a rotation axis parallel to the longitudinal axis. The flow deflector has a flow channel therethrough having an intake bore at a front end of the flow deflector and a discharge bore at a rear end of the flow deflector. The intake bore is coaxial with the rotation axis and the discharge bore is offset from the rotation axis.
