摘要： A pressure balanced rotary valve can be made more compact if the ports on the stator within can be located on a port pitch circle of smaller diameter. In certain circumstances for rotary valves used in pressure swing adsorption devices, it is acceptable for the spacing between the ports to be made smaller than the ports themselves. In a rotary valve comprising variable loading means (e.g. pistons) and fixed loading means (e.g. springs), this can involve reducing the piston size and increasing the load provided by the springs.
摘要翻译：如果定子内部的端口可以位于较小直径的端口节圆上，则可以使压力平衡旋转阀更紧凑。在用于变压吸附装置的旋转阀的某些情况下，端口之间的间隔可以比端口本身小。在包括可变加载装置（例如活塞）和固定装载装置（例如弹簧）的旋转阀中，这可以涉及减小活塞尺寸并增加由弹簧提供的载荷。

摘要： The four-way selector valve relating to the invention basically comprises a motor which has a stator and a rotor, a case, and a main body including a main valve and a valve seat, both of which are arranged in a valve chest within the case. The valve seat has a suction pressure passage and a discharge pressure passage, which lead to a suction port of a compressor and a discharge port thereof, respectively, and two passage holes which lead to indoor and outdoor heat exchangers, respectively. The main valve has a connecting part which selectively leads to one of the suction pressure passage and the two passage holes, and a pressure equalization orifice which links the connecting part and the valve chest. A rotor sleeve, which comprises the rotor, is equipped with an auxiliary valve which opens or closes the pressure equalization orifice in order to transfer pressure, and an operating pin which moves the position of the main valve. The rotor of the motor rotates the auxiliary valve on the main valve and slides the main valve on the valve seat via the operating pin.

A bulkhead is provided on a bottom surface of the high pressure connecting groove and both end portions of the high pressure connecting groove open to an inner surface of the valve housing through respective high pressure fluid jetting grooves so as to hold stable the main valve element at the first or second channel-switching position. Flow of high pressure fluid jetting to the high pressure connecting groove is then disturbed by the bulkhead, difference in power between flow of the high pressure fluid jetting from the both end portions of the high pressure connecting groove to the periphery of the main valve element through the respective high pressure fluid jetting grooves arises and brings about rotating force to the main valve element, and thus the main valve element being in rotation can surely get to a due channel-switching position.

摘要： A reversing valve for a vapor compression refrigeration system comprising a housing defining a chamber with a high pressure port, a low pressure port and first and second system ports opening into said chamber through a chamber wall; a valve member disposed in the housing for shifting movement generally parallel to the wall between a first position wherein the valve member communicates the low pressure port with the first system port while communicating the high pressure port with the second system port and a second position wherein the valve member communicates the low pressure port with the second system port while communicating the high pressure port with the first system port, the valve member blocking communication between the high and low pressure ports when in the first and second positions; the valve member subjected to a net differential pressure force acting to firmly seat the valve member in the first or second position for preventing leakage between the high pressure port and the low pressure port; and, an actuator for reversing the direction of the net differential pressure force acting on the valve member to unseat the valve member and move it away from its first or second position for facilitating the shifting movement to the other position.

摘要： A channel-switching valve into which a high-pressure liquid and a low-pressure liquid flow is provided. The channel-switching valve includes a stator and a rotor which has a surface in contact with one surface of the stator and rotates while sliding on the contact surface. The stator has a plurality of liquid flow ports open to the contact surface, and the rotor has a plurality of channel grooves for connecting the liquid flow ports. One of the channel grooves is a straight groove passing through the rotational center of the rotor, and the other channel grooves are line-symmetrically arranged with respect to the straight channel groove. Alternatively, among the channel grooves, the channel grooves into which the high-pressure liquid flows are configured to be located on both sides of the rotational center of the rotor. As a result, a local load acting on the rotor during a high-pressure liquid-feeding process is reduced, so that the contact surface is prevented from being scraped off by the edge of the opening of a port during the rotation of the rotor.
