The invention concerns a delivery valve for the delivery of a fluid into a tank of a motor vehicle. According to the invention, the following is provided: a) the delivery valve has a first settable maximum volume flow, b) the delivery valve has a second settable maximum volume flow which is higher than the first settable maximum volume flow, c) a control device (24, 25), by means of which optionally the first or the second maximum volume flow can be set, d) a sensor device (20, 21), which is configured for interaction with a signal emitter (29) assigned to the tank of the motor vehicle and which activates the control device.

A fill valve system with a float nested in a container connected to the fill valve and a siphon device passing water out of the container into the toilet tank, with the siphon device having an air vent dimensioned such that: (i) tank refilling is delayed until after the flush valve closes; (ii) the fill valve is not turned on by small leaks in the tank; and (iii) the fill valve turns off when it encounters large leaks in the tank.

A vehicle fueling control system according to an exemplary aspect of the present disclosure includes, among other things, a fuel inlet conduit configured to receive a fuel dispensing nozzle, and a blocking assembly. The blocking assembly is configured to move back and forth between a fill blocking position that blocks airflow through a port of the fuel dispensing nozzle and a fill permitting position that permits airflow through the port of the fuel dispensing nozzle.

A fill valve with pressure chamber having an open bottom end and a diaphragm at a top end such that falling water level in the toilet tank causes the diaphragm to flex in a first direction, thereby moving a sealing member to an open position, with a venturi in the fill valve keeping the sealing member in the open position until water refilling the tank causes the diaphragm to flex in a second direction, thereby moving the sealing member back to the closed position.

A flow diverter for diverting flow between a toilet bowl and a toilet tank, having: a body having an inlet, a first outlet and a second outlet; and a flow adjustment mechanism rotatable within the body to selectively divert different percentages of flow between the first outlet and the second outlet; and an air vent and diaphragm in the body to prevent a siphon flow from the first or second outlet back to the inlet.
