摘要： A valve section for a hydraulic system includes at least a first hydraulic port and a second hydraulic port, a spool, a pressure channel, a collector channel, an inlet pressure compensator disposed between the pressure channel and the spool, and an outlet pressure compensator disposed between the spool and the collector channel. The spool selectively connects the first hydraulic port to the pressure channel and the second hydraulic port to the collector channel or connects the first hydraulic port to the collector channel and the second hydraulic port to the pressure channel. The inlet pressure compensator and the outlet pressure compensator are controllable via a signal pressure device. An external additional force component dependent on an operating state of the hydraulic system acts on the hydraulic port connected to the collector channel on the signal pressure device such that the inlet pressure compensator blocks the pressure channel.

摘要： Fluid pressure reduction devices for use in gas and liquid handling systems are disclosed. An example fluid pressure reduction device includes a plurality of cylinders, each having an inner diameter surface and an outer diameter surface and a plurality of apertures that extend from the inner diameter surface to the outer diameter surface. The cylinders are arranged in a nested configuration so that a substantial portion of the inner diameter surface of one of the plurality of cylinders is in contact with a substantial portion of the outer diameter surface of another one of the cylinders. Portions of the apertures of one of the cylinders overlap at least portions of the apertures of another one of the cylinders to form a process fluid flow path.

摘要： Heating/defrost constructions of a very low temperature refrigeration system having a defrost supply circuit and a defrost return bypass circuit optimizing the heating/defrost cycle, preventing overload (excessive pressure) of its refrigeration process and protecting components from damaging temperatures. The defrost cycle operates continuously, when required, and provides a shorter recovery period between heating/defrost and cooling operating modes. The rate of the temperature change during cool down or warm up is controlled in an open loop fashion by controlled refrigerant flow in bypass circuits.

摘要： A flow compensator valve for use in a hydraulic system which includes a cylindrical body having inlet and outlet ports, and a slidable, spring-biased hollow piston insert disposed within a center bore of the body, which insert has a plurality of ports for flow control depending on the position of the insert as it reciprocates axially within the center bore of the valve body. In a preferred embodiment, the valve is used in connection with a hydraulically actuated lift which is particularly useful for assistance of handicap persons for vans and mass transit vehicles. The axially-reciprocable, spring-biased flow rate controlling insert has a small central axial bore for slow lift movement in the loaded condition and at least one larger transverse bore, which when exposed, permits flow therethrough for faster movement of the lift in the unloaded condition.
