Abstract

A rotary valve includes a rotor housing having a first centrally-located aperture extending axially through the rotor housing, an inlet port, and an outlet port. The inlet port and the outlet port each extend radially and open into the first centrally-located aperture. The rotary valve further includes a rotor to be disposed within the first centrally-located aperture. The rotor includes a main body and a dwell space extending radially inwardly into the main body and circumferentially around a portion of the main body. The rotor further includes a second centrally-located aperture that extends axially through a distal end of the rotor and into the dwell space within the main body.
