  • Patent number: 9157540
    Abstract: A fluid flow control device includes a regulator for operating at high pressures and an integral bypass valve. The regulator and the bypass valve each include a control assembly that is movable between an open position and a closed position. The regulator and bypass valves are biased into the open positions and adapted to move into the closed positions when an operating pressure rises to above respective regulator and bypass set-point pressures. The bypass set-point pressure is lower than the regulator set-point pressure such that when the operating pressure rises above the bypass set-point pressure, the bypass valve automatically closes and allows the regulator to perform under normal operating conditions. So configured, the bypass valve is arranged to accommodate at least some of the fluid flow through the system until the operating pressure reaches the normal operating pressure, which is somewhere between the bypass and regulator set-point pressures.

    Abstract: To reduce collision noise created by the operation of an electromagnetic suction valve provided on a high pressure fuel supply pump. In the present invention, in order to achieve the above object, the mass of a member which collides by magnetic attractive force is reduced to reduce the noise to be generated. The thus configured present invention provides the following advantageous effects. The noise generated when a core and an anchor collide with each other by magnetic attractive force depends on the magnitude of the kinetic energy of a moving element. The kinetic energy to be consumed in the collision is only the kinetic energy of the anchor. The kinetic energy of a rod, being absorbed by a spring, does not contribute to the noise; thus, the energy when the anchor and the core collide with each other can be reduced, whereby the noise to be created can be reduced.

    Abstract: A vacuum pump connected to a unit where a low pressure is desired to be maintained, is adapted to reduce a rise in its temperature, during extended operations of the pump. A suction channel has a first end connected to a suction port of the pump and a second end connected to the unit. An aperture provided on the suction channel extends to a pre-determined depth with the channel. The aperture is plugged by a fusible material, or a material capable of subliming. As the temperature of the pump rises, the suction channel transfers heat to the plugging layer of the aperture, and the layer melts or sublimes gradually, with the temperature rise. Once the layer has completely melted or sublimed, the apertures aspirate ambient air from the surroundings into the pump, which cools the interior components of the pump, and quickly reduces the pump's temperature.

    Abstract: In an engine having an oil pump wherein an oil filter is incorporated into the oil pump without allowing the oil pump to become large in size. An oil pump and a hydraulic line changeover valve including a spool valve are disposed so as to have axes extending in parallel with each other. The oil pump has a plate-shaped oil filter disposed at a discharge port thereof. The plate-shaped oil filter is curved arcuately along an outer periphery of a pump rotor as viewed from a pump axial direction.

    Abstract: The present invention relates to an improved mechanical pumping hydraulic unit for use in oil production or hydrocarbon extraction. The unit is characterized in that it has one motor (1-25), which activates a dual pump (1-15) at one end of the shaft and activates a fan (1-26) at the opposite end of the same shaft. The dual pump (1-15) provides power to the hydraulic power circuit (1-13) and to the hydraulic recirculation circuit (1-14). The motor (1-25), along with the pump (1-15) and the fan (1-26), are inside a metal structure (1-8), or focusing element, which serves to propel air sent by the fan (1-26) through the radiator (1-14-3) and to protect all the components of said unit, such as a tank (1-3) for the hydraulic oil, a compartment or casing for the electrical components (1-5), and a component or dry chamber (1-2) for the hydraulic instrument panel (1-7).

  • Publication number: 20130209276
    Abstract: The invention relates to a hydraulic system comprising a source of high pressure (A), a consumer (C) connectable to the source of high pressure (A) via a flow control valve (21), and a solenoid valve (22) arranged to control the flow control valve (21). The hydraulic system further comprises a hydraulic pilot valve (31) selectively controllable by the solenoid valve (22) to connect a control chamber (28) in the flow control valve (21) either to the source of high pressure (A) or to a low pressure side (T). When the solenoid valve (22) is actuated, the consumer (C) is pre-pressurized via a by-pass conduit prior to the opening of the flow control valve (21). At the same time, the source of high pressure (A) is arranged to act on a first and a second end (32, 33) of the hydraulic pilot valve (31) wherein a spring (36) is arranged to displace the hydraulic pilot valve (31) and connect the control chamber (28) to the low pressure side (T) to open the flow control valve (21).

  • Patent number: 8505506
    Abstract: An oil pressure control apparatus includes a control valve mechanism being in communication with a pump via a first fluid passage and being in communication with a control apparatus via a second fluid passage, a third fluid passage diverging from the first fluid passage to supply oil to a predetermined portion other than the control apparatus, and a fluid passage dimension regulating mechanism including a movable member provided at the third fluid passage and including an opening for regulating a fluid passage dimension of the third fluid passage. The fluid passage dimension regulating mechanism is in communication with a fourth fluid passage diverging from the second fluid passage and biases the movable member to a side increasing the fluid passage dimension by applying the hydraulic pressure of the fourth fluid passage to the movable member separately from the hydraulic pressure of the third fluid passage.

  • Publication number: 20130183167
    Abstract: An operational control device is disclosed for a positive-displacement pump having a motor, means for actuating the motor, state sensor means for detecting an actual operating parameter (e.g., pressure) of the pump, and operating mode means for controlling an operating mode of the pump. A first actuating mode of the operating mode means is set by the actuating means below a first operating-parameter threshold value (P1). This mode brings about a constantly rising pump pressure in the direction of an operating-parameter setpoint value (Pset) in a variable manner, which is dependent on a detected change in the operating parameter over a predefined time interval. A second actuating mode is set as normal operation to the operating-parameter setpoint value by the actuating means above the first operating-parameter threshold value. P1 is fixed or is calculated as a fraction of the operating-parameter setpoint value and/or a pump parameter correlated therewith.

  • Publication number: 20130121853
    Abstract: A pump system especially suitable for pumping out liquids from tank enclosures. A liquid pump, Preferably powered by pressurized gas such as compressed air or natural gas from a nearby well, is mounted in a tubular member frame. The rate of pressurized gas flowing to the pump, and consequently the liquid pumping rate, is controlled by a limit valve, lever arm, and float assembly. As the liquid level increases, the float rises and the lever arm opens the limit valve, permitting a higher rate of pressurized gas flow and higher pump rate. At least some components of the frame have liquid inlet openings, which permit liquids to enter the frame, and the frame serves as a conduit to carry the liquids to the intake of the pump.
