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 flow diverter for diverting flow between a toilet bowl and a toilet tank, the flow diverter having: a body with an inlet, outlet and pressure relief vent; and a flow adjustment mechanism rotatable around the outlet to selectively divert different percentages of flow between the outlet and the pressure relief vent by moving a stopper in and out of the outlet by rotating a sleeve of the flow adjustment mechanism around the outlet.

A nozzle for dispensing fluid including a nozzle body having a spout and fluid path through which fluid to be dispensed is flowable. The nozzle includes an actuator configured to detect when the spout is sufficiently inserted into a fluid receptacle, and a shut-off device configured to selectively terminate or prevent fluid dispensing operations through the fluid path. The nozzle further includes an interlock operatively coupling the actuator to the shut-off device. The interlock includes a slider that is operatively coupled to the actuator and a pivotable arm that is operatively coupled to the shut-off device, and the slider is slidable along the arm.

An attitude sensing arrangement for triggering a shutoff mechanism on a fuel dispensing nozzle comprising a rolling element placed inside a non-cylindrical chamber that is sealed with a plug such that the rolling element may move freely inside the chamber. A vacuum sensing path passes from a sensing port in the nozzle spout, through a vacuum sensing tube, into the non-cylindrical chamber, and into a venturi-generated vacuum chamber. The attitude sensing arrangement is configured such that the rolling element blocks a shutoff port in the non-cylindrical chamber when the nozzle is raised past a certain shutoff angle. When the vacuum sensing path is blocked by the rolling element in this manner, the shutoff mechanism closes the main fuel valve.

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.

Disclosed is a method and apparatus for the dispensing of liquids (e.g., fuel) where the apparatus and method include an improved nozzle that reduces residual liquid retained in the nozzle when dispensing is stopped.

A filling nozzle, comprising an inlet (13) for the connection of a fluid supply line, an outlet (14) for dispensing the fluid, a fluid channel (15), a coupling device (22) for converting a movement of a hand lever (17) into an actuation of a main valve (16) and a membrane (26) which separates a first membrane space (27) from a second membrane space (28) and which can be moved to actuate the coupling device (22) by a pressure difference existing between the first membrane space (27) and the second membrane space (28). A vacuum can be applied to the first membrane space (27), wherein a sensor line (19) opens into the first membrane space (27). The second membrane space (28) is sealed with respect to the fluid channel (15) and is fluidically connected via a ventilation channel (29) to the surroundings outside the filling nozzle, wherein the fluid flows around a part of the coupling device (22) situated outside the second membrane space (28) when the main valve (16) is opened.

The present invention relates to a nozzle for dispensing a fluid, with an inlet (2) for the connection of a fluid feed line, a main channel (16) which connects the inlet (2) to an outlet (25), with a main valve (5) for controlling a total volumetric flow through the main channel (16), and with a vacuum line (9) which opens into the main channel (16). According to the invention, the main channel (16) merges downstream of the main valve (5) into a part channel (10) and into at least one bypass channel (20a-20e) which runs parallel to the part channel (10), the part channel (10) and/or the at least one bypass channel (20a-20e) having means for prioritizing the fluid throughflow, which means are configured in such a way that a relative proportion of the total volumetric flow which flows through the part channel (10) decreases as the total volumetric flow increases, the part channel (10) having a tapered portion (33), and the vacuum line (9) opening in the region of the tapered portion (33) into the part channel (10). The vacuum generation is considerably improved by virtue of the part channel according to the invention, with the result that the reliability of an automatic switch-off device which is loaded by the vacuum is improved.
