    摘要： A valve for controlling fluid flow in a fluid system is disclosed. The valve includes a housing, a servo spool, and a piston. The servo spool defines a spiral groove and a spiral land. The piston defines an orifice configured to provide flow communication to a supply of pressurized fluid and an orifice configured to provide flow communication to a portion of the fluid system exterior to the valve. The valve further includes a main spool operably coupled to the piston. The main spool is configured to control flow of fluid in the fluid system. The spiral groove and spiral land are configured such that angular displacement of the servo spool results in a force imbalance on the piston, thereby moving the piston and the main spool in one of a first direction and a second direction.

    摘要翻译： 公开了一种用于控制流体系统中的流体流动的阀。 阀包括壳体，伺服卷轴和活塞。 伺服卷轴限定螺旋槽和螺旋槽。 活塞限定了一个孔口，其构造成提供与加压流体供应的流动连通，以及构造成提供与该阀外部流体系统的一部分的流动连通的孔口。 阀还包括可操作地联接到活塞的主阀芯。 主阀芯被配置为控制流体系统中的流体流动。 螺旋槽和螺旋槽脊构造成使得伺服阀芯的角位移导致活塞上的力不平衡，从而使活塞和主阀芯在第一方向和第二方向中的一个方向上移动。

    摘要： An inflatable product has an air pump device and a pressure releasing valve. The air pump device has a housing and a pumping assembly. The housing has two openings as an inlet opening and an outlet opening. The pumping assembly is mounted in the housing and has a motor and a fan. The motor is mounted between the inlet and outlet openings and drives the fan. Consequently, mounting the motor between the first opening and the second opening dissipates the heat of the motor because the air passing by the motor cools the motor. The pressure releasing valve is adjusted by users and releases air while pressure of air in the inflatable body reaches a predetermined pressure level.

    摘要： A casing accommodates therein a movable valve adapted to be moved away from a valve seat by a hydraulic oil flowing through an oil-hydraulic circuit from a hydraulic cylinder to an oil-hydraulic pump. In an event of oscillatory hydraulic pressures in the hydraulic cylinder, the hydraulic oil is returned through the oil-hydraulic circuit from the hydraulic cylinder to the oil-hydraulic pump via a second port, a communication path, a minor gap between the movable valve and the valve seat, and a first port. In this process, the communication path allows for a smooth flow of the hydraulic oil from the second port into the movable valve.

    摘要： An apparatus for mixing and activating polymer which includes the introduction of gas with water and polymer in order to create a variable density type foam which aids in the activation and enhances the efficiency of the polymer. The apparatus of the preferred embodiment provides the introduction of water and polymer into a mixing loop having a premixing manifold containing a static mixer, injecting or sparging gas into the outflow from the static mixer, blending and activating by mechanical agitation the water polymer and gas mixture, partially feeding back into the mixing loop the mixture to provide a desired level of polymer activation which is delivered at a desired rate of flow. This system provides capabilities for selecting the desired level of activation, levels of polymer concentration, levels of overall flow rate as well as controlling the various energy imparting elements of the apparatus.

    摘要： Fluid flow through a conduit is controlled by varying the pressure of the fluid. The fluid passes through a normally closed valve comprising a flexible sleeve held in pinched closed condition by an elastic material which is isolated from all pressures except those transmitted through the sleeve.
