An assembly of a drain plug for a dishwasher is disclosed, comprising a hollow stem portion and a drain plug body. A double O-ring is provided to seat and seal the ball body into a drain pipe, and to make a light, sliding fit with the interior of the drain pipe. The sliding fit guides the assembly during vertical movement and enables the assembly to maintain a vertical position without tilting. When the O-rings become worn, they are replaced, rather than having to discard the entire assembly.

A distributor, notably for use in a sprinkling or like system, for causing a liquid to flow successively through a first orifice, then through a second orifice, but only after a predetermined quantity of liquid has passed through the first orifice. This distributor comprises a volumetric metering device comprising a piston movable in a first direction under the influence of the liquid pressure from the inlet orifice to a first orifice via an open valve, a chamber and a passage. A piston comprises a rod provided with a push member capable of moving a control member in the first direction, this control member being then driven for rotation by a driving member coupled kinematically to a turbine. Simultaneously, the driving body closes the valve and after a predetermined rotation of the control member the cavity thereof registers with the push member and the rod can move freely in the first direction and close the first outlet orifice while opening the second outlet orifice.

A duct system is provided with a pair of branch conduits each having a differential pressure operated valve. Two sets of pressure ducts are connected to the duct system and a plug member is caused to shuttle back and forth, in controlled fashion to expose one or the other sets of pressure ducts to high internal fluid pressure. Each set of pressure ducts is connected so that valve-closing operation is effected for one valve and valve-opening operation is effected for the other valve in response to high internal fluid pressure in such ducts, so that the plug will cause one valve to be open when it is held in a position between the two sets of ducts until it is released to move beyond both sets of ducts thereby to cause said one valve to close, and vice versa.

A heating system can include certain pressure sensitive features. These features can be configured to change from a first position to a second position based on a pressure of a fuel flowing into the feature. These features can include, fuel selector valves, pressure regulators, burner nozzles, and oxygen depletion sensor nozzles, among other features.
