  • Patent number: 9856975
    Abstract: A hydraulic system for actuating an interlocking shifting element of a transmission which comprises two piston chambers and a piston element that delimits the piston chambers. The piston element can be acted upon in one piston chamber by a pressure to open the shifting element and, in the other piston chamber, by another pressure to close the shifting element. Pressure can be delivered by a valve to two piston chamber and the valve can be actuated by an actuator by a pilot pressure. The valve and the electro-hydraulic actuator are designed and functionally connected to one another such that, in the event of a pressure drop, a total hydraulic force, acting to close the shifting element, is applied to the piston element and, if the current supply to the actuator fails, a total hydraulic force acting, in the opening direction of the shifting element, acts upon the piston element.

  • Patent number: 9803777
    Abstract: An attenuating device that is configured to replace motion converters in conventional control valve assemblies. The attenuating device can generate an output displacement in response to a position of a plug relative to a seat in the valve assembly. In one embodiment, the attenuating device comprises a spring assembly with a pair of spring members, disposed in series, and configured to assume a deflection that reduces the displacement of the plug to a smaller displacement that is useful to position a target member of a sensor. This embodiment, however, forgoes the mechanisms of conventional devices in lieu of components that are amenable to compact design. In this way, the attenuating device can substantially fit within the existing structure of the valve assembly, and, in one construction, the attenuating device is disposed in the actuator of the valve assembly.

The actuating device has an axially movable actuating rod which is connected to a coupling element which for its part is connected via a pivot pin to an actuation section of a bypass valve, the actuation section being configured as a lever arm. In order to set the desired closed position of the bypass valve during a predefined actuation of the actuating device, the coupling element is first connected to the actuating rod while still being displaceable. Before the fixing, the position of the actuating device which corresponds to the closed position is set by application of the corresponding voltage to the electric actuating device. Subsequently, a prestressing force is applied to the coupling element coaxially with respect to the actuating rod via a pneumatic actuator.

  • Patent number: 8708306
    Abstract: A tunable valve assembly reduces valve-generated vibration. One embodiment comprises a valve body and valve seat having substantially collinear longitudinal axes. A rebound characteristic frequency is associated with rebound of the elastic valve body base plate from forceful contact with the valve seat. A central cavity in the valve body encloses a spring-mass damper optionally immersed in a dilatant liquid and having a damper resonant frequency approximating a pump housing resonance. A lateral support assembly adjustably secured to the valve seat has a support resonant frequency designed in conjunction with the rebound characteristic frequency and the damper resonant frequency. Combined hysteresis heat loss associated with the above three vibration frequencies is reflected in lower closing energy impulse amplitude and damping of associated vibrations.

    Abstract: A clutch mechanism for a slurry valve, wherein the slurry valve has a valve seat for seating a valve closure member carried on a valve stem, a drive member threadably engaged with the valve stem, the drive member being rotatable relative to the valve stem to axially move the valve stem and closure member relative to the valve seat to open and close the slurry valve, and a driving means for rotating the drive member, the clutch mechanism comprising: a clutch body having an internally threaded bore for threadably receiving the valve stem; and clamping means actuable with the clutch body for clamping the clutch body to the driving means so as to lock the valve stem and drive member together and allow them to rotate in unison to grind scale from the valve seat and valve closure member when they are positioned against each other.

  • Patent number: 7918435
    Abstract: A combination gravimetric and volumetric fluid dispenser which includes a scale linked to a controller. The controller is linked to a plurality of two stage valves which control the dispensing of large quantities of base materials. The controller is also linked to a plurality of nutating pumps which together with the controller controls the dispensing of smaller quantities of additive materials. The base material dispensing valves include stepper motor actuators having multiple steps per revolution and are under the control of an analog signal from a controller. The base material dispensing valve is opened or closed via a rod that is slidably raised or lowered upon rotation of the drive shaft of the stepper motor actuator.

  • Patent number: 7905249
    Abstract: An electromagnetic proportional pressure-control valve of a vehicle transmission which includes a magnet part, a hydraulic part and a spring operatively connecting the magnet part to the hydraulic part. The magnet part includes a coil, an armature and an armature bar. The hydraulic part includes first and second closing elements. The first closing element forms a flat seat and the second closing element a ball seat and the closing elements are opened and/or closed via a tappet rod. When no current is applied to the valve, the second closing element is closed and an gap (ü) in the first closing element is larger than one seventh a nominal width (NW) of the valve. The second closure area (A_2) is larger than a circular area having a diameter corresponding to double the gap and the diameter (s) of the tappet rod is smaller than 0.7 times the diameter (b) of the orifice.

  • Patent number: 7878480
    Abstract: A solenoid valve, particularly of the type to be used for controlling a hydraulic system for variable actuation of the valves of an internal-combustion engine, has a valve element co-operating with a valve seat and a pusher element, separate from the valve element, which is pushed against the valve element by the movable core of the solenoid valve when the solenoid of the solenoid valve is energized in order to bring the valve element into contact with the valve seat. After de-energization of the solenoid, the time necessary for bringing back the pusher element into the resting condition in contact with the valve element is reduced thanks to the application of a braking current to the solenoid of the solenoid valve during the stage in which the movable core and the pusher element associated thereto displace in the direction opposite to the direction of the movement generated by the magnetic field of the solenoid, following upon de-energization of the solenoid valve.

  • Publication number: 20100276011
    Abstract: An improved sequencing fluid control valve comprising a housing having inlet and outlet ports, a valve seat disposed within the housing, a collapsible valve member disposed within the housing and forming a chamber and a bulb. A sequencing means disposed within the chamber that controls the axial motion of the valve member in response to application of fluid pressure at the inlet such that the motion of valve member alternates between an open free flowing state and a closed restricted flow state. Housing and valve member cooperate in the open position to provide an annular flow path that does not require the fluid flow direction to substantially change while flowing from inlet to outlet. Housing and valve member bulb cooperate in the closed position to form a circumferential seal to restrict the fluid flow. Alternative embodiments including viscous damping means and variations on the housing mount are described.

  • Patent number: 7819378
    Abstract: A gate valve has a gate that moves in a gate cavity between a lower closed position and an upper open position. A seal member in the gate seals against a downstream seat ring when the gate is in the closed position. The seal member is moveable in upward and downward directions as well as upstream and downstream directions relative to the gate. The seal member is in an upper and downstream position relative to the gate while the gate is in the closed position. A cam member is carried by the gate for movement in unison and is in engagement with the seal member. The cam member moves the seal member to an upstream and downward position in response to initial movement of the gate from the closed position toward the open position.
