摘要： An integrated pressure regulator is provided with three stages configured to reduce an extreme tank pressure down to a typical working pressure. The regulator is configured to supply a steady working pressure until the tank pressure is reduced to little more than the working pressure itself. Stages of the pressure regulator are integrated into a body and arranged to minimize regulator mass and volume. A thermally-triggered pressure relief device may be included with a triggering time adapted to enhance the safety of smaller cylinders that may be used, e.g., in aerial applications.

摘要： A hydraulic pressure regulating device for variable line pressure control is provided which comprises a valve housing, a sleeve, an adjustment screw assembly, a spring, and a valve spool. The valve housing defines a chamber therein. The sleeve is disposed in the chamber and is provided with a spring-receiving hole in one side thereof, and a projection portion is formed on an outer circumference of the sleeve to contact an inner surface of the valve housing. The adjustment screw assembly is configured to be able to adjust a position of the sleeve, and the sleeve is supported by the adjust screw assembly. One end of the spring is inserted into the spring-receiving hole such that the spring is supported by the sleeve. The valve spool is disposed in the chamber to be driven by a hydraulic pressure supplied into the chamber, and it is elastically supported by the spring.

摘要： A preselection valve is for a hydraulic valve assembly with a switching element, a pressure input line, a first pressure output line and a first load pressure line with a load pressure inlet and output. The switching element is switchable from neutral to a first switching position. The pressure input line is connected to the first pressure output line in the first position. The preselection valve has a second and third load pressure line and a load pressure increasing device. The second load pressure line branches off the pressure input line upstream of the switching element. The load pressure increasing device is connected to the third load pressure line, which connects the pressure increasing device to the first load pressure line. The second load pressure line is connected to the pressure increasing device in the first switching position and the second load pressure line is blocked in the neutral position.

摘要： A proportional valve is provided having a pilot control valve that can be controlled by means of a control signal and having a booster valve that can be actuated by means of the pilot control valve. The proportional valve has a compressed-air connection for connecting a compressed-air supply, a working connection, and an air-removal connection. The booster valve has three valve elements, which are arranged one after the other and can each be moved in an axial direction against a spring force.
