Abstract
A flow valve for a fuel supply system is arranged in a supply line leading to an internal combustion engine and, in a basic position upon the start of the internal combustion engine, closes a branch line which leads to a sucking-jet pump. For this purpose the flow valve has a closure member which is displaceable substantially transverse to the direction of flow by the flow of the fuel.
Claims15
A flow valve for a fuel supply system having a fuel tank and a sucking-jet pump, wherein a fuel device is located in the fuel tank for feeding fuel via a fuel line to an internal combustion engine, the valve comprising:
- a main channel forming part of the fuel line, a closure member, a branch line, a connection on the main channel for receiving the branch line, and a valve seat disposed in the connection;
- wherein the main channel is a part of the connection, the branch line leads to the sucking-jet pump, and the closure member is disposed in the connection for controlling fluid flow in the branch line, the closure member is arranged in the main channel and has a basic position for closing the valve seat of the connection;
- a passage is developed within the connection to provide a throttle point for fuel flowing to the internal combustion engine, the passage being arranged between the closure member and a wall of the main channel;
- and
- moving means are located within the connection for moving the closure member in a direction transverse to a direction of fluid flow in the main channel.
A flow valve for a fluid supply system, the system comprising a tank, a sucking-jet pump, and a feed device located in the fuel tank for feeding fluid via a feed line away from the tank, the valve comprising:
- a main channel forming part of the feed line, a closure member, a branch line, a connection on the main channel for receiving the branch line, and a valve seat disposed in the connection;
- wherein the main channel is a part of the connection, the branch line leads to the sucking-jet pump, and the closure member is disposed in the connection for controlling fluid flow in the branch line;
- a passage is developed by movement of the closure member within the connection between the closure member and a wall of the connection to provide a throttle point for flowing fluid;
- and
- moving means are located within the connection for urging the closure member to move in a direction transverse to a direction of fluid flow in the main channel.
