Multi-way reversing valve

摘要

A multi-way reversing valve includes a valve housing having a valve seat part in which a plurality of fluid in/out ports are formed; a valve member adapted to be rotated; and an actuator adapted to rotationally actuate the valve member. A fluid inlet port and/or a fluid outlet port is/are formed in the valve housing. A passage adapted to selectively place the fluid inlet port or the fluid outlet port in communication with the plurality of fluid in/out ports is formed within the valve member. Flow paths are reversed by rotating the valve member to selectively place the fluid inlet port or the fluid outlet port in communication with one of the plurality of in/out ports via the passage. The rotational axis line of the valve member is laterally eccentric relative to the rotational axis line of an output shaft of the actuator by a predetermined distance.

1. A multi-way reversing valve, comprising:
a valve housing in which a valve chamber and at least three ports that lead to the valve chamber are provided; a valve member rotatably provided in the valve chamber so as to selectively place one of the ports in communication with one of the remaining plurality of ports; an actuator adapted to rotate the valve member; and a cylindrical shaft bearing member; wherein the valve member is supported on one side by the valve housing; wherein a rotational axis line of the valve member is laterally eccentric relative to a rotational axis line of an output shaft of the actuator by a predetermined distance; and wherein the cylindrical shaft bearing member is supported on one side by the valve housing and one end part or both end parts of the valve member is/are slidably and rotatably fitted around the outer circumference of the cylindrical shaft bearing member.
