Abstract
A flow limiting valve, comprising a valve body adjustable between a closed position and an open position, wherein in the open position a flow channel for a conveying fluid is opened in the flow limiting valve and in the closed position the flow channel is closed, whereby the adjustment of the valve body is subject to conveying fluid pressure; wherein a control valve is integrated into a housing of the flow limiting valve through which the valve body is adjustable between open and closed positions, regardless of the conveying fluid.
Claims15
A flow control valve for a dual injection system, the flow control valve comprising:
- a housing;
- a valve body adjustable between a closed position and an open position, wherein in the open position a flow channel for a burnable gas is opened in the flow control valve and in the closed position the flow channel is closed, whereby the movement of the valve body is subject to pressure of a liquid fuel used as a control fluid or in the absence of the liquid fuel used as the control fluid;
- and
- a control valve integrated into the housing of the flow control valve through which the valve body is moveable between open and closed positions, regardless of the burnable gas.
A dual injection system, comprising:
- a flow limiting valve, including:
- a gas chamber in fluid connection with a connecting element configured to receive a burnable gas as a conveying fluid;
- an outlet channel;
- a control valve integrated into a housing, the control including:
- a valve body adjustable between a closed position and an open position, the adjustment operable by pressure of liquid fuel used as a control fluid or in the absence of the liquid fuel used as the control fluid;
- and
- a flow channel in the valve body for passage of the conveying fluid, the flow channel being opened between the gas chamber and the outlet channel in the open position and closed in the closed position;
- a burnable gas injector unit configured to control a flow of burnable gas;
- and
- a liquid fuel injector unit configured to control a flow of liquid fuel.
A method of operating a dual-injection system, comprising:
- providing a flow limiting valve, including:
- a gas chamber in fluid connection with a connecting element configured to receive a conveying fluid;
- an outlet channel;
- a control valve integrated into a housing, the control valve including:
- a valve body adjustable between a closed position and an open position, the adjustment operable by pressure of a conveying fluid or in the absence of the conveying fluid;
- and
- a flow channel in the valve body for passage of the conveying fluid, the flow channel being opened between the gas chamber and the outlet channel in the open position and closed in the closed position;
- a burnable gas injector unit configured to control a flow of burnable gas;
- and
- a liquid fuel injector unit configured to control a flow of liquid fuel;
- providing a liquid fuel used as a control fluid;
- and
- adjusting the control valve with pressure of the control fluid.
