Abstract
The invention concerns a bidirectional air release valve for the tank system of a motor vehicle having an inlet opening, an outlet opening, a valve seat placed between the openings, and a closure element, which in its closed position blocks the flow communication between the inlet and outlet openings and in its opened position releases the blockage. The closure element is activated by a motor such that it may be adjusted to bring about optional intervening positions.
Claims21
A bi-directional air valve for a the tank system of a motor vehicle, the air valve comprising:
- an inlet port;
- an outlet port;
- a sealing valve seat disposed between the inlet and outlet ports;
- a motor;
- and
- a closure element controllable by the motor, the closure element being configured to seat about the sealing valve to block a flow between the inlet and outlet ports in a closed position and being further configured to unseat from about the sealing valve seat to permit the flow in an open position, wherein the closure element is controllable by the motor to be set at intervening positions between the closed and open positions.
A bi-directional air valve for a motor vehicle tank system, the bi-directional air valve comprising:
- a housing defining an inlet port therethrough and an outlet port therethrough, the inlet port in communication with a fuel tank interior and in controlled communication with the outlet port;
- a valve seat defined about the inlet port;
- a motor connected to the housing;
- a transmission defining a closure element thereon, the transmission connected to the motor, the motor being configured to drive the transmission to move the closing element into a closed position about the valve seat to close communication between the inlet port and the outlet port and to move the closing element away from the valve seat to open communication between the inlet port and the outlet port.
