摘要： A distributing device having a housing having an inlet connection and a plurality of outlet connections, and an electromotively drivable, rotatably adjustable distributor which is arranged therein in the form of a disk, on which a liquid receiving and liquid guiding device is formed. The distributing disk is rotatably adjustable into defined positions relative to the housing. The liquid receiving and liquid guiding device includes a front radial groove which controls the liquid to the desired locations of the distributing device. The radial groove is in the form of an open profile and extends from an external face, on the radial circumference, of the distributing disk into the distributing disk. The inlet connection supplies pressurized liquid to a radial gap which the distributing disk forms with the housing at the radial circumference and which guides the liquid to the radial groove. A liquid-distributing actuator includes such a distributing device.

摘要： A multifunctional filter valve is provided. The multifunctional filter valve includes a valve body, a rotatable valve plate, a fixed valve plate, and a driving device. A water inlet, a water outlet, and a drainage outlet are disposed on a side wall of the valve body. The water outlet is configured to connect to a valve. An inner chamber and an outer chamber are defined in the valve body. The inner chamber defines a central drainage chamber, a working chamber, a backward washing chamber, and a blind chamber. A first filter element interface and a second filter element interface are defined at a bottom of the valve body. The combination of fixed valve plate and rotatable valve plate achieves a normal operation mode, a backward washing mode, and a forward washing mode. The multifunctional filter valve has a simpler structure and lower production cost.

摘要： A rotary valve of a cryocooler includes a valve stator, a valve rotor, a rotation member that rotates the valve rotor around an axis with respect to the valve stator, and a rotor holder connected to the valve rotor so as to rotate around an axis together with the valve rotor, and forming a low pressure section having a pressure lower than an ambient pressure between the valve rotor and the rotor holder so as to reduce an axial force of pressing the valve rotor against the valve stator. The rotation member is connected to the rotor holder so as to rotate the valve rotor around the axis via the rotor holder. The rotor holder is disposed between the rotation member and the valve rotor in an axial direction, and is movable in the axial direction with respect to the rotation member.

摘要： A synchronous switch valve core with a voltage stabilizing function, comprising: a valve core housing (1), a valve core base (2), a flow regulating module, and a balancing hydraulic module. The flow regulating module is capable of cutting off a cold/hot water path before water enters a pressure balancing module, thus preventing high-temperature water from immersing the valve core, preventing the building of lime scale, protecting the valve core, and extending the service life; moreover, water flow can enter the pressure balancing module only after flowing through the flow regulating module, thus preventing the channeling of hot and cold, and obviating the need to install a check valve at a water intake elbow. By means of an optimized design with respect to the parts of the synchronous switch valve core, the synchronous valve core is transformed from a switch capable only of regulating flow into a switch not only capable of regulating flow but also capable of synchronized switching, and also capable of balancing the pressures within two channels, thus transforming a product equipped with the vale core from a complex channel into a simple channel, and obviating the need for separately providing a balancing module part; a valve body is structurally simple, has a shortened water path, and is inexpensive.

摘要： A sanitary valve having a main valve with a diaphragm movable between closed and open positions. The main valve is in an inner housing rotatably mounted in an outer housing. The inner housing has a first valve opening connected to a first valve opening in the outer housing to form a valve outlet. The inner housing has a second valve opening arranged on the outside relative to the valve outlet and is paired with a second valve opening in the outer housing forming a valve inlet. Paired second valve openings are brought into congruence by a relative twisting of the inner and outer housings with the valve inlet being variable. The inner housing has a pot-base inside from which a valve connector protrudes which connects the inner part first valve opening forming the valve outlet to the valve seat formed by the free sleeve end region of the valve connector.

摘要： A self-pressure-relief air distribution mechanism includes an air distribution valve (6) where a rear face of the air distribution valve (6) is divided into a high-pressure face (66) and a low-pressure face (65), each hermetically separated by a third sealing ring (b3) that seals the air distribution valve (6) and a cover (2). A low-pressure passage (22) of the cover (2) can communicate with the rear face of the air distribution valve (6) via a pressure-relief hole (61), to guide a low-pressure airflow in the cover (2) to the rear face of the air distribution valve (6). A cryogenic refrigerator includes the self-pressure-relief air distribution mechanism. With the provision of the pressure-relief hole (61) and the third sealing ring (b3), the self-pressure-relief air distribution mechanism has a reduced pressure receiving area, thereby reducing a positive acting force and reducing wear.
