  • Patent number: 9546735
    Abstract: A double-seat valve has a seat-cleaning function and ensures that the seat-cleaning flow is conducted into and out of the leakage hollow space with as little turbulence as possible. The valve reliably prevents a pressure-increasing direct action upon the seat regions, even in the event that the cross-sectional area of the drain bore is smaller than that of the largest pipeline that can be connected to the valve. This is achieved in that a region of extension of the deflection surface that faces away from the radially outer end of the deflection surface delimits the remaining region of the opening in its entirety and opens out from the second closing element at an end-face and radially inner end of the second closing element, facing the first closing element.

  • Patent number: 7644724
    Abstract: The invention relates to an assembly comprising an electromechanical device and a self-sealing valve, and in particular, to any inflatable device that includes the assembly. In one embodiment, the assembly comprises a valve housing defining an opening through which fluid can be provided to the inflatable device, a flexible diaphragm assembly that is configured to self-seal the opening with sufficient fluid pressure in the inflatable device and to open under sufficient fluid pressure from a fluid moving device, to provide fluid through the opening to and seal the inflatable device. The assembly further comprises an electromechanical device including an actuating arm, having a first position in which the actuating arm urges open the self-sealing valve and a second position in which the actuating arm does not act upon the self-sealing valve, so as to regulate an amount of fluid within the inflatable device. With this arrangement, a small, low power, low duty cycle electromechanical device can be used.

  • Publication number: 20090014072
    Abstract: An internal valve (10, 10? or 10?) and its methods of use for stabilizing and reinforcing inflatable objects are disclosed. The internal valve is a novel, simple modification to conventional check valves with the addition of a discharging means for external control (14, 22 or 28). An internal supplemental chamber comprises one or more partitions that are secured, directly or by I-beams (40?), to main chamber's walls (40) of an inflatable object and stretched when the main chamber is inflated. With the internal valve as the passage to and from the main chamber, the enclosed or isolated supplemental chamber (30, 30?, 32, 34, 36 or 38) functions as a stabilizing or reinforcing component. A plurality of chambers 36 can form cylinder beams for an inflatable mattress.

  • Patent number: 7469713
    Abstract: A check valve for an inflatable device comprising a poppet urged by a conical spring to annularly seal uniformly around its entire periphery to assure more uniform cracking pressure about its entire periphery. In one embodiment the check valve comprises a locking key to lock the valve closed irrespective of the cracking pressure that may otherwise may have cracked the valve open. In another embodiment, the check valve comprises a manual dump feature that allows rapid dumping of air from the inflatable irrespective of low cracking pressure that may exist in the inflatable.

  • Patent number: 7357152
    Abstract: The invention relates to a releasable non-return valve, in which a connection between a working chamber and a connector chamber may be closed by a non-return piston and opened by the opening movement of a release piston which may be pressurized with a release pressure. The non-return piston, discharge piston and release piston are arranged concentric to each other with the release shaft in the common valve axis. The valve has a cartridge embodiment with a non-return valve cartridge which may be inserted in the valve housing and a discharge valve cartridge independent of the non-return valve cartridge. The release shaft extends through the non-return piston with a sliding seal and engages behind the piston base by means of a stepped diameter for opening. The discharge piston is pressure compensated on both sides by pressurization with the working pressure.

  • Patent number: 7273065
    Abstract: A valve assembly for a dunnage bag wherein in the valve body a valve diaphragm is mounted on a shaft and is supported by a mounting bar such that the valve diaphragm may be reciprocally moved from the closed position to the open position by a simple axial push on the valve shaft. The valve shaft is retained in the mounting bar in an orifice and the shaft diameter is enlarged at its end distant from the valve diaphragm so as to generate a frictional force fit or lock in the open position to facilitate the removal of air from the bag. The valve may be released form the friction lock by the air pressure of a recharged bag and/or by the manual movement of the valve diaphragm and shaft axially toward the open end of the valve assembly.

  • Patent number: 7270145
    Abstract: The invention relates to valves for air compressors, and more particularly, to an unloading/venting valve having integrated therewith a high-pressure protection valve where a pressure reducing valve has a discharge port in communication with the air system and a vent. The valve utilizes a valve body biased to form a seal between the discharge port and the vent. A governor monitors the air pressure in the system and generates a signal to move the valve body against the bias and unloads the system when a first predetermined threshold pressure is reached. In the event of a failure of the valve body to move at the first threshold pressure, the valve body is movable against the bias in response to a second predetermined threshold pressure reached in the system, thereby unloading the system.

  • Patent number: 7178554
    Abstract: An ultrasonically operated valve a source of ultrasonic energy for excitation of a pressurized liquid. The vibration of the ultrasonic horn imparts a pulsing of the pressure of the liquid within the valve. Selection of a sealing mechanism that responds at a different natural frequency than that of the valve body causes the sealing mechanism to unseat and therefore to enable liquid flow. The sealing mechanism will stay unseated as long as the source is imparting energy to the system and therefore inducing pressure pulses in the liquid thus keeping the sealing mechanism away from the valve seat.

  • Patent number: 6938597
    Abstract: Disclosed herein is a variable spring force intake valve for use in two- or four-stroke internal combustion engines. The device comprises an intake valve body and a torsion spring attached to a gear and rod assembly. Manipulation, via manual or automated means, of the gear and rod assembly adjusts the tension/torsion force exerted by the torsion spring to preload the intake valve and/or to hold the intake valve in the closed position. Varying the tension/torsion force results in an ability to control the timing and the degree to which the ports of the intake valve are actually opened during the operating cycle of the piston, thereby providing a user with an opportunity to enhance the operation of a two- or four-stroke internal combustion engine.
