  • Publication number: 20130255802
    Abstract: A valve and a hydraulic controller are provider. The valve may combine a rotary-to-linear converter with the hydraulic controller to provide for at least two mechanisms for actuating the valve. Additionally, the valve may include a mechanical lock mechanism suitable for securing the valve at a desired flow position. The mechanical lock mechanism may also provide overload protection. That is, the mechanical lock mechanism may “slip” or disengage if torque forces reach undesired levels. The hydraulic controller may enable a “stepping” mode of control and “fast actuation” mode of control. The “stepping” mode may deliver a discrete quantity of a fluid, while the “fast actuation” mode may deliver a continuous quantity of the fluid.

  • Publication number: 20130240765
    Abstract: A frequency unit valve is provided. In the frequency valve, a free piston reciprocates within a housing where a sub-valve is mounted in a lower portion. Variable frequency units installed above and under the free piston provide a damping characteristic by selectively opening or closing a passage when a frequency of a piston rod is in a high-frequency region and a low-frequency region. Accordingly, the vehicle ride comfort is maximally improved.

  • Publication number: 20130233396
    Abstract: A hydraulic valve for a vehicle transmission includes a housing, a valve piston, an actuating piston, and a bi-stable spring. The housing is connectable with an inlet passage and an outlet passage for the transmission. The valve piston is sealed to the housing and selectively blocks a fluid flow between the inlet passage and the outlet passage. The actuating piston is sealed to the housing and is arranged to be displaceable by a hydraulic pressure in the inlet passage. The bi-stable spring is engaged with the valve piston and the actuating piston. In some example embodiments, the bi-stable spring is axially fixed with regards to the valve piston and displaceable by the actuating piston.

    Abstract: A driving and adjusting device of a passive shuttle-type shut-off valve is provided. The problems of a big valve body structure size, a non-random angle installment, a single drive mode, low stability and reliability, a high temperature and poisonous material entering into the driving and adjusting device and unadjustable on-off speed and low volume in the prior device are solved. A main body (33) is connected with an upstream pipe (1) and a downstream pipe (3). A pressure port (2) on the upstream pipe (1) is connected with the driving device. A double acting cylinder (34) is provided in a valve sleeve (21). The left and right chambers of the double acting cylinder are connected with the valve clack (24). The driving device is composed of a regulating valve, a directional valve, a check valve, a boost-insulation valve and an accumulator (18). It can select the drive mode and adjust the on-off speed and the flow volume of the valve.

  • Patent number: 8469057
    Abstract: A valve includes a valve cap, a valve body, a diaphragm, biasing means and a locking mechanism. The valve cap includes a plurality of process conduits and process ports. The valve body faces the valve cap and includes a plurality of plunger passages extending therein. The diaphragm is positioned between the valve cap and the valve body. The valve body includes a plunger assembly, a first support structure and a second support structure. The plunger assembly includes a plurality of plungers, each slidable between a closed position and an open position. In the closed position, the plunger deforms the diaphragm in order to block communication between two of the process ports. In the open position, the plunger is retracted away from the diaphragm. Each plunger is either a normally closed plunger or a normally open plunger. The normally closed plungers are mounted upon first support structure and the normally open plungers are mounted upon the second support structure.

  • Patent number: 8469333
    Abstract: A valve actuator assembly, counter-biased by a working fluid (or gas) pressure, is disclosed. The valve actuator assembly comprises a valve and a pneumatic or hydraulic actuator. A port is defined axially through the valve and actuator that communicates a working fluid (or gas) pressure acting on the valve face to a counter-biasing chamber inside an actuator housing. This design eliminates, reduces, or overcomes a force acting on a face of the valve by communicating a common working pressure of the fluid (or gas) to a substrate on the actuator with a resultant force vector opposite the valve face.

  • Patent number: 8413486
    Abstract: The shut-off valve testing system provides for the testing of the main shut-off valve of a combustible gas supply line in such facilities as refineries, factories, or other plants utilizing such gaseous fuel. The system includes a combination hydraulic-pneumatic cylinder receiving pneumatic pressure from a suitable source, the cylinder communicating hydraulically with a hydraulic actuator for the main shut-off valve. The system provides for testing of the shut-off valve by actuating the valve through a portion of its full travel, thus confirming that the valve is free. This is accomplished by shutting off the pneumatic pressure to one side of the hydraulic-pneumatic cylinder, and opening the hydraulic line between the cylinder and the actuator. Thus, hydraulic pressure from the actuator can bleed to the cylinder, allowing the actuator to move to the extent of the limiting spring and/or pneumatic pressure to the opposite side of the cylinder.
