  • Flow control valve
    Patent number: 7219690
    Abstract: A two-stage fluid pressure control valve has five components. An inlet socket with separate fluid flow orifices sealably engages an outlet socket which also has separate fluid flow orifices. A pressure check piston having a fluid flow orifice along its longitudinal central axis slidably engages the inlet socket and the outlet socket. A spring located along the central axis of the outlet socket biases the pressure check piston in an open position, allowing fluid to flow through all orifices. Fluid flow through the control valve may impact the pressure check piston to overcome the spring force, moving the pressure check piston to a closed position, whereby fluid flows only through the orifice in the pressure check piston.

  • Pressure regulating valve for common rail fuel injection systems
    Patent number: 7216669
    Abstract: A pressure regulating valve for regulating the pressure in a common rail with a pistonlike valve member which is guided axially displaceably in a bore and acts in the closing direction on a closing element and presses it against a valve seat; the valve member forms an armature of an electromagnet to which electrical current can be supplied. The opening cross section of the inlet of the pressure regulating valve is designed such that the pressure regulating valve cannot be opened until beyond a predetermined minimum fuel pressure greater than or equal two 250 bar. In this way, even if the electromagnetic closing force fails, a minimum pressure at the valve outlet is generated and thus makes an injection event possible.

  • Self-contained oxygen generator
    Patent number: 7195028
    Abstract: A self-contained oxygen generator containing a PSA unit and a flowmeter in the outlet line. The flowmeter provides a signal which represents the flow rate of the oxygen in the outlet line. A leakage circuit with a calibrated orifice and a solenoid valve are also located on the outlet line. In response to a signal from the flowmeter, the solenoid can be actuated so as to provide a calibrated leakage at the outlet of the PSA. This calibrated leakage is useful when overall oxygen usage is too low.

  • Modulating bypass control system and method
    Patent number: 7178545
    Abstract: A control system for a bypass duct includes a pneumatic damper control assembly, a sensor and a pneumatic switch. The damper control assembly includes a damper vane mountable in the bypass duct for movement between relative open and closed positions to regulate airflow through the bypass duct. The position of the damper vane is controllable via pressure applied through a damper control line. The sensor is mountable to the supply duct to transmit a pneumatic supply duct signal via a supply line based on at least one of air pressure or air velocity in the supply duct. Finally, the pneumatic switch opens or closes the connection between the damper control line and the supply line based on the difference between (1) the pneumatic supply duct signal via the supply line, and (2) the combination of the pneumatic pressure from the damper assembly and a switch biasing pressure.

  • Flow control device and system
    Patent number: 7171981
    Abstract: A flow control valve has a ball and an annular seat providing a positive stop for automatically preventing flow through the valve when a line downstream has been broken. The flow control valve is useful for interior applications in which seepage through the valve would be unacceptable and in which both hot and cold water lines need to be protected. A magnet may aid in positioning the ball. Sensors may be used to detect positions of the ball. A flow control system that includes the flow control valve may include any of a variety of interchangeable components for facilitating incorporation of the flow control valve in a water or other fluid line. Another embodiment includes a mechanism for detecting and stopping flow due to slow leaks.

  • High impact discharge valve
    Patent number: 7168446
    Abstract: A check valve for use in a pump. The valve is arranged to be subjected to severe service conditions and high impact loads, yet be resistant to damage to its components. The check includes a body, a valve seat, a poppet and an impact cushion. The poppet is movably coupled to the valve seat and is biased by a spring into engagement with the valve seat. Upon the opening of the valve the poppet moves off of the valve seat and into engagement with the impact cushion against the spring bias. The impact cushion is movably coupled to the valve body and is biased by another spring. When the poppet engages the impact cushion they stay together and move, with the movement of the impact cushion absorbing energy from the poppet.
