  • Patent number: 9234605
    Abstract: A constant pressure valve includes a lock rod, a valve sleeve, a sliding shaft, a biasing unit, and a solenoid unit. The lock rod is formed with a first through hole. The valve sleeve is inserted fixedly into the lock rod, and includes an outer sleeve surface having a shrunk surface portion cooperating with the lock rod to define an annular space in fluid communication with the first through hole. The sliding shaft is movable in the valve sleeve to contact the lock rod, and includes a large-diameter section and a small-diameter section. The constant pressure valve is adapted to maintain a hydraulic device at a preset pressure. The less a difference between the diameters of the large-diameter section and the small-diameter section is, the more the preset pressure can be.

  • Patent number: 8656948
    Abstract: A wide variety of machines have moveable members that are operated by an hydraulic actuator. For example, an internal combustion engine has a camshaft which is mechanically coupled to rotate with the crankshaft and which opens and closes cylinder intake and exhaust valves. Traditionally the camshaft timing was fixed at a setting that produced the best operation for all engine operating conditions. However, it has been recognized that engine performance can be improved if the valve timing varies as a function of engine speed, engine load, and other factors. Thus a hydraulic actuator is being used on some engines to vary the coupling relationship of the camshaft to the crankshaft. A solenoid operated valve controls the application of pressurized fluid to operate the hydraulic actuator.

  • Patent number: 6840272
    Abstract: A fuel-conditioning device for removing moisture from fuel includes two replaceable fuel-conditioning cartridges. The cartridges are alternately put in use by selectively positioning a valve actuator. A marking system for the fuel-conditioning cartridges and the valve actuator identifies which cartridge is in use and which can be serviced. A cartridge can be replaced while maintaining a continuous flow of fuel.

  • Patent number: 6818122
    Abstract: A replaceable cartridge type dual stage bypass valve is used in dual filter multi-media filtration assemblies. The cartridge may be selected and easily replaced to meet the various combinations and requirements of the dual filter elements (primary and secondary). The individual bypass valves that form the dual stage bypass valve may each be responsive to a predetermined increase of pressure due to a clogged filter condition. The individual bypass valves may use replaceable coil springs. The spring force of the coil spring is determined by the pressure differential to be resisted, i.e., the resistance to be offered by the spring action of the spring, and the flow capacity at a given pressure differential.

  • Patent number: 6627077
    Abstract: A multi-part filter combination is received in a stepped bore of a fluid-carrying component. A larger-diameter filter part is associated with a larger-diameter bore portion, and a smaller-diameter filter part is associated with a smaller-diameter bore portion. The two filter parts of the filter combination are connected by a connecting part. When the two filter parts are joined in their respective final position in the bore, this connecting part is detachable by means of a die to be introduced into the bore. The filter combination can be used in a valve block serving to receive a magnet valve.

  • Patent number: 6540028
    Abstract: A pressure operated normally closed control valve operates to open at a predetermined pressure between the system minimum and maximum pressures to open the valve and allow the discharge of condensate from the system which has a source of pressure to provide a minimum and a maximum pressure. The system is subject to the formation of condensate. There is an inline filter at the inlet end of the valve and a discharge nozzle at the outlet end of the valve. The entrance to the discharge nozzle may also have a filter. The assembly can also be arranged so that the control valve is normally open and operates to open at a predetermined pressure at or below the system minimum pressure whereby condensate is removed, and to close the valve and prevent the discharge of condensate from the system when the pressure falls below the predetermined pressure.

  • Patent number: 6536470
    Abstract: A back flow prevention valve for preventing water from draining back into a water supply line. The back flow prevention valve includes a housing comprising a tubular body having a first and second open end each having a respective covering thereon with an aperture extending therethrough. A water supply pipe is fluidly coupled to the aperture in a first covering. A cylinder is coupled to the first covering and extends inward of the tubular body. A piston having a bore extending therethrough is slidably positioned in the cylinder. A biasing member biases the piston toward the first covering. The aperture in the second covering has a ledge therein for opening the valve. A one-way valve is removably coupled to the piston and is adapted for letting water move outwardly through the piston toward the second end of the tubular member.
