    摘要: A rotory servovalve is constructed with a cylindrical annular housing and a cylindrical valve element rotatable therewithin. The valve housing has at least two inlet orifices, at least two outlet orifices, at least two first fluid transfer control orifices, and at least two second fluid transfer control orifices. At least two orifices of each type are located on opposite sides of the valve housing from each other. Preferably there is a first end orifice, a central orifice, and a second end orifice of each type. The end orifices of each type are angularly and longitudinally aligned with each other and are angularly offset 180 degrees from a central orifice of the same type. The end orifices of each type have an area equal to one-half the area of the central orifice of the same type and are equally spaced in opposite longitudinal directions from the central orifice of the same type. An imbalance of fluid forces within the servovalve mechanism is thereby avoided, both in a direction perpendicular to the valve axis and in planes passing through and containing the valve axis. By eliminating force imbalances within the valve in high-pressure applications the electrical current requirement and the mass of the components required for the driving motor or rotory solenoid that operates the valve are reduced.

    摘要: A fitting, particularly a tap cock, for receptacles such as tank trucks or containers, which includes a housing (2), having an inlet opening (12) and an outlet opening (14), and a rotatable body (4) with a through passageway (48), having an inflow opening (50) and an outflow opening (52). The rotatable body (4) is rotatably disposed in the housing such that when rotated into an open position it facilitates fluid communication between the inlet opening (12) and the outlet opening (14) and when rotated into a closed position, it shuts off such communication. The fitting of the invention enables a large throughput during loading and unloading of the receptacle with little structural change by providing the rotatable body (4) with a second inflow opening (54) having a cross-section at least approximately the same size as the first inflow opening (50), and by providing the housing (2) with a bearing ring (46) or a seat ring (82) in the vicinity of the second inflow opening (54).

    摘要: This invention relates to a hydraulic, multi-way distributor comprising a body (10) with a water inlet passage (11) and several water outlet ways (12) towards just as many uses. A rotary diverter device (13) in said body is provided with an axial hole (16′) communicating with the water inlet passage and a lateral opening (16) designed to be positioned far away from or fully or partially in line with at least one of said outlet ways, in order to intercept the inlet water flow and to distribute water flow towards said uses, selectively.

    摘要: The present invention relates to a rotary valve assembly for a pressure swing adsorption system. The rotary valve assembly includes a first valve member and a second valve member relatively rotatable about a common center of rotation to provide valving action for selectively transferring fluids therethrough. The second valve member has a first fluid section with at least one aperture adapted for transferring a first fluid of a first pressure and composition therethrough and a second fluid section with at least one aperture adapted for transferring a second fluid of a second pressure and composition therethrough. The first valve member has a first fluid section with at least one passage for transferring the first fluid in the valve assembly and a second fluid section with at least one passage for transferring the second fluid in the valve assembly. A vent is located between the first fluid sections and the second fluid sections of the valve assembly and is vented to a pressure lower than the pressures of the first and second fluids so as to vent leakage from either of the sections of the valve assembly. The rotary valve assembly further includes means for effecting relative rotation of the first valve member and second valve member.
