摘要： A four-way switching valve device which comprises a valve chamber provided with at least a liquid inflow port and a liquid flow-direction switching means comprising a plurality of liquid inflow and outflow ports and a first valve slidably mounted on the liquid flow-direction switching means to selectively communicate one of the liquid inflow and outflow ports to a liquid outflow port respectively. A second valve is fixedly mounted on at least one end of a connecting rod extending longitudinally inside the valve chamber from the first valve and sliding hermetically inside of the valve chamber, and a thermosensitive slow acting operation device is provided at at least one end of the valve chamber and opposite to the second valve, and further, a switching device for controlling at least the inflow of the high pressure liquid into a cavity formed between the second valve and the slow acting operation device in the valve chamber is provided, the switching device being actuated directly or indirectly by a working rod of the slow acting operation device to thereby cause the high pressure liquid to flow into the cavity to move the first valve, whereby one of the plurality of liquid inflow and outflow ports in the liquid flow-direction switching means is selected to switch the communication to the liquid outflow port. The four way switching valve device of this invention has not only a simple construction but also a small size, providing a greater handling ease and reduced production costs, and therefore, can be widely used in many industrial fields. Further, the operating environment can be improved because the noise of the impulse sound generated during operation is substantially eliminated.
