摘要： A pressure regulator has a valve tube assembly, a gas-input assembly, a first regulating assembly and a second regulating assembly. The gas storage device has a storage unit and the pressure regulator. By the first and the second regulating assemblies, the effect of adjusting down the gas pressure is achieved to maintain the safety of use. The pressure regulator is partially embedded in the gas storage unit to reduce the overall volume of the gas storage device. However, the high-pressure piston chamber of the valve tube assembly communicates with the outside of the gas storage unit through the high-pressure gas channel to maintain the normal operation of the elastic element in the high-pressure piston chamber.

摘要： A flow control valve for a bathing installation. The flow control valve is configured to operate between an open state and a closed state in dependence on the applied water pressure. As water pressure increases, the valve progressively reduces flow dynamically, until flow increases to a point that the valve is placed in the closed state. The valve may be placed in the bathing installation recirculating water path downstream of a bypass path and upstream of a heat pump. By regulating water flow and pressure to the heat pump, the heat pump may be operated in a flow rate for efficient operation. The valve also prevents water pressure at a high level which may damage the heat pump.

摘要： A spool valve (1) includes: a sleeve (10) extending in an axial direction thereof, including an inlet port (11) and an outlet port for working fluid; a spool (20) movably housed in the sleeve (10) in the axial direction; a biasing device (30) including a spring (31) as a biasing member configured to press a base end (20a) of the spool (20) toward a tip end (20b) of the spool (20); and a pressure detecting port (56) for the working fluid, opening toward the tip end (20b) of the spool (20). The outlet port (12) is constituted of slits (16), and the slits (16) are arranged at intervals in the circumferential direction of the sleeve (10) and extended in the axial direction.

摘要： Example implementations relate to a pressure regulator assembly for a closed fluid loop of a CDU. The pressure regulator assembly has a cylinder having an internal volume, and first and second hollow pistons slidably connected to the cylinder to split the internal volume into a first volume portion having cooling fluid, a second volume portion having driver fluid, and a third volume portion having compressible matter. The first volume portion is fluidically connected to the closed fluid loop. The first hollow piston is reciprocated by the compressible matter to maintain operating pressure of the cooling fluid in the closed fluid loop. The second hollow piston is driven by the driver fluid in response to predefined pressure drop of the cooling fluid during predefined time period, to inject additional cooling fluid from the first volume portion into the closed fluid loop to restore pressure level of cooling fluid to operating pressure.

摘要： A pneumatic pressure control valve for a brake control system of a rail vehicle includes a first pressure chamber to which a brake pressure can be applied, and a second pressure chamber to which a predetermined, adjustable pressure can be applied, wherein the first pressure chamber and the second pressure chamber are sealed off with respect to one another via a pressure compensation piston, and wherein the pressure compensation piston is designed to open a flow connection from the first pressure compensation chamber to a ventilation duct when the effect of the pressure on the pressure compensation piston in the first pressure chamber is greater than the effect of the pressure on the pressure compensation piston in the second pressure chamber.

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 gas regulator includes a valve chamber body that houses two valves of the regulator. Valve elements that move to open and close the two valves are received via a same opening into the valve chamber body, which is closed by a plug. The plug can define a first valve seat as well as a piercing element used to pierce a compressed gas cylinder. A retainer can hold a gasket at a valve seat as well as provide a bore or other support for a valve element and valve element spring.

摘要： Example implementations relate to an accumulator for regulating variations in operating pressure of a cool fluid in a closed fluid loop of a coolant distribution unit (CDU). The accumulator includes a cylinder having an internal volume defined between an inlet and outlet, and a hollow piston slidably connected to the cylinder through one of the inlet or outlet to split the internal volume into a first volume portion filled with the cool fluid and a second volume portion filled with a compressible matter that is maintained at the operating pressure by the cool fluid filled in the first volume portion via the hollow piston. The first volume portion is fluidically connected to the closed fluid loop functioning at the operating pressure via the hollow piston and other one of the inlet or the outlet to direct a flow of the cool fluid into the closed fluid loop via the accumulator.
