摘要： A device for controlling the opening and the closure of a valve includes rotatable element configured to control the position of the rotary valve on the basis of its rotation in a direction or in the opposite direction; and a system that causes the rotation of the rotatable element and includes two antagonist feeder conduits that generate a linear motion. The rotatable element is shaped as a pulley and the system that causes the rotation further includes a wire anchored to the pulley and to the feeder conduits to cause the rotation in a direction or in the opposite direction of the pulley based on the application of a pre-determined traction on the wire obtained through the linear motion generated by the feeder conduits.

摘要： A valve assembly for a pump driven by a motor is provided. The motor has an output shaft for driving the pump. The valve assembly includes a valve element concentrically attached to the output shaft of the motor. The valve assembly includes a gear set mounted on the output shaft of the motor. The gear set provides a motive force to the valve element through the output shaft for axially translating between an open position and a closed position on the output shaft. A spring located between the gear set and the valve element biases the valve element against the motive force provided by the gear set.

摘要： An integrated multifunctional valve device includes a surface member having a first port and a second port formed therein, a flexible disk member having a central portion and a surrounding portion, a first seat member extending outward from the surface member and coupled to the surrounding portion of the flexible disk member, a second seat member extending outward from the surface member and surrounded by the first seat member. The central portion is movable between an open port position to establish fluid communication between the respective ports and a close port position to stop the fluid communication between the respective ports. The second seat member is configured to selectively receive the central portion of the flexible disk member corresponding to the close port position. The integrated multifunctional valve device also includes an actuator member configured to selectively move the central portion of the flexible disk member into the open port position and the close port position.

摘要： A gauge assembly includes an indicator for providing an indication of an amount of fluid in a tank and a stop-fill assembly for stopping the flow of fluid flowing into the tank once the fluid reaches a particular level. The gauge assembly has a shaft that rotates as the fluid level changes in the tank. The indicator translates the rotational position of the shaft into a fluid level. The stop-fill assembly moves from an open position, where fluid can flow into the tank, to a closed position, where fluid is prohibited from flowing into the tank, depending on the rotational position of the shaft.

摘要： A dual locking valve assembly includes two check valve elements in two cartridge bores. Each check valve element opens to permit forward flow of fluid under pressure in the cartridge bore from an input bore to an output bore. The check valve element closes to block back flow of fluid under pressure in the cartridge bore from the output bore towards the input bore. The back flow of fluid under pressure exerts a closing force upon the check valve element from within the output chamber. A counter force generating element, or pilot element, communicates with the valve element, to selectively open the valve, even in the presence of back flow pressure. The pilot element exists as a fluid crossover path from one cartridge bore to the other.
