  • Patent number: 10393280
    Abstract: A seat valve with electromagnetic actuation combines, in one device, the functions of a seat valve, of a pressure-limiting valve and optionally also of one or more check valves. Furthermore, the switching noise of the seat valve function is reduced. In a de-energized state of an electromagnet, a fluid flow from a port P to a port TNC occurs only if a pressure difference between the ports P and TNC exceeds a limit value of ?pG, wherein the force of the specified pressure difference overcomes the force of a spring and therefore pushes a first sealing body out of a first sealing seat, and in the energized state of the electromagnet, a fluid flow from port P to port TNC occurs even in the case of a pressure difference less than ?pG if the force of the electromagnet together with the force of the pressure difference between the ports P and TNC overcomes the force of the spring, wherein the sum of the specified forces pushes the first sealing body out of the first sealing seat.

    Abstract: A fluid supply system includes a fluid supply source, a first valve unit, a second valve unit, a first pressure detector, a second pressure detector, a third pressure detector, and a controller. If the pressure detected by the third pressure detector is less than a shutoff pressure at a timing of starting supply of fluid from the fluid supply source, the controller calculates a pressure equalization time from a timing at which opening of a pilot valve is completed to a timing at which a main valve starts closing, based on the pressures detected by the first pressure detector, the second pressure detector and the third pressure detector, sets a valve-open waiting time based on the pressure equalization time, and controls opening of the second valve unit upon elapse of the valve-open waiting time after controlling opening of the first valve unit.

  • Patent number: 8678029
    Abstract: A pressure regulator includes a housing assembly defining a main fluid flow path from an inlet end to an outlet end. A tubular plunger body is supported within the housing assembly for linear movement toward and away from a valve seat in response to fluid pressure at said outlet end. An actuator sleeve is supported within the housing assembly and engaged with the tubular plunger body, and a pressure chamber defined in part by a shut-off diaphragm extends between the housing assembly and the actuator sleeve. A fluid port is arranged to supply pressurized fluid to the pressure chamber to thereby produce linear movement of the actuator sleeve and the tubular plunger body independent of the pressure at said outlet end, moving the tubular plunger body into engagement with the valve seat to shut off the flow path.

  • Patent number: 8561632
    Abstract: A quick-acting valve 1 having metering relief is used in particular for oxygen lances, wherein the actual sealing body 10 inside the valve tube 2 has a two-part design and accommodates the valve spring 8 with the housing parts 16 and 17 of the spring. The gas is conducted around the sealing body 10, so that the gas pressure cannot have an effect on the actuation by way of the hand lever 3. The rear housing part 17, which is located behind the front housing part 16 can be displaced inside the front housing part 16, and has a flow-promoting design, being displaced against the force of the valve spring 8, and specifically with the help of the hand lever 3, so that it now can be actuated independently of the gas pressure with precise metering control.
