Abstract: A duel fuel gas control valve controls the supply of gas (e.g., natural gas or liquid propane gas) to a gas grill. The duel fuel gas control valve is structured to control either natural or LP gas flow at the desired operating characteristics based on conventional gas supply characteristics and gas grill requirements. A restrictor mechanism, when in first and second configurations, respectively, restricts movement of the valve core to a first predetermined range for a first mode of operation (first type of gas supply) and to a second predetermined range for a second mode of operation (second type of gas supply).

Abstract: A unitary slot valve actuator is in a vacuum body between process and transport modules. A separate valve is provided on the unitary actuator for each of two valve slots, each slot being closed or opened according to the position of the unitary actuator. The separate valves allow a vacuum condition to be maintained in the transport module while an adjacent process module is open to the atmosphere for servicing. Access to both open valves for servicing is by centering the unitary actuator to hold both valves open, but not vertically-spaced, relative to the slots. The open valves are easily reached by a service worker through an access port. A computer workstation operates a controller for the slot closure, and for moving the unitary actuator and the valves from the open and centered position, away from the slots to expose seal surfaces around the slots for cleaning.

Abstract: A unitary slot valve actuator is in a vacuum body between adjacent vacuum chambers, such as process and transport modules. Separate valves are provided on the unitary actuator for each of two valve slots, each slot being closed or opened according to the position of the unitary actuator. The separate valves allow a vacuum condition to be maintained in the transport module while an adjacent process module is open to the atmosphere for servicing. The unitary actuator allows access to an open valve for servicing the open valve by way of a centering mechanism that holds the valves in an open, but not vertically-spaced, position relative to the slots. The open valves are easily reached by a service worker. A separate motor moves the unitary actuator and the valves down from the open position and away from the slots to expose seal surfaces around the slots for cleaning.

Abstract: A valve comprises an inlet and two outlets. The flow to the two outlets is controlled by an integrated valve having two members which operate in conjunction with the two valve seats associated with the outlets. The valve is used in an air-assisted fuel-injection system of an internal-combustion engine, wherein the first outlet of the valve is connected to a bypass of a throttle valve of the engine, and the second outlet of the valve is connected to an air-assisted fuel injector of the fuel-injection system. In this manner, both the atomization of the fuel injected by the fuel injector and the idling speed of the engine are controlled by a single valve.

Abstract: A valve body comprises a first sealing seat and a second seat opposite the first. The valve element is selectively controlled so that, in addition to the position in which a bearing surface thereof rests on the first seat to ensure tightness of the device and of the circuit on which it is mounted, the valve element can be placed in a median position between the two seats, so as to provide a maximum flowing section between the valve element and the valve body for draining the circuit. In intermediate positions, another bearing surface of the valve element works in cooperation with the second seat, the valve element being held in a position selected between the first median position and a resting position on the second seat, thus limiting the flowing section between the valve element and the second seat to control the discharge of the circuit.
