A multi-position valve assembly including a valve housing, a stator element and a rotor element rotatably mounted about a rotational axis. The valve assembly further includes a pressure adjustment assembly movable between a release position and a stop position, hard stopped relative to the valve housing. The pressure adjustment assembly includes a pressure adjuster device configured to movably cooperate between the rotor element and the valve housing to adjustably generate an axial compression pressure at the rotor-stator interface at a calibrated operating pressure, PC. When the pressure adjustment assembly is oriented in the release position, the axial compression pressure is substantially removed from the rotor-stator interface. In contrast, when the pressure adjustment assembly is oriented in the stop position, the axial compression pressure is substantially reproduced at the calibrated operating pressure, PC. |
