Abstract: Apparatus is provided for use as an in-line fluid flow monitor through filter media of a variety typically employed in domestic applications upstream of a kitchen faucet as well as unusually low pressure water supplies. Apparatus includes an outer housing with an input port leading to a rotatable turbine within the housing. The turbine, rotatable about a longitudinal axis, is coupled to an offset gear which, in turn, is coupled to a reduction gear train which includes first and second gear arrays mounted for rotation about a first and second axis located parallel with and spaced from the longitudinal axis. Fluid communication is provided from the turbine chamber through the gear train to an output port. The gear train ends in an output which is engaged in driving relationship with an oppositely disposed rotatable valve member having resilient pawl legs extending therefrom. The pawls are configured to engage the output to provide rotatable ratcheting movement.

Abstract: Apparatus is provided for use as an in-line fluid flow monitor through filter media of a variety typically employed in households upstream of a kitchen faucet. The apparatus includes a housing with an input port leading to a housing cap within which a turbine chamber retains a rotating turbine. The rotating turbine is coupled to a reduction gear train positioned within a gear housing, in turn, retained within the body of the housing in a reduction gear chamber. Fluid communication is provided from the turbine chamber to the gear reduction chamber. The gear reduction chamber ends in an eccentric output which drives the pawl of a pawl and ratchet assembly forming a part of a rotatable valve. This rotatable valve rotates in increments as a camming stem affixed thereto moves along a camming surface until encountering a slot component.

Abstract: A valve device for directing hard water past a softening means and for further mixing hard water with soft water. A double headed first valve is slidably mounted within the tubular shaped main body of the valve device and is separated internally therefrom forming a bypass passage extending from the hard water inlet to the main outlet. An external control knob is operable to move the valve from the closed position to an open position. A second valve extends through the first valve and is movable by a second control to and from the first valve to allow hard water to pass through the closed first valve from the hard water inlet to the soft water outlet to control mixing of hard water with soft water.

Abstract: A lever actuated valve stem for control of liquid flow through a filtering device. The device is connectable to a source of impure liquids and includes a filter disposed between the inlet and the outlet of the device for the removal of the impurities. The valve stem is operable to direct fluid flow through the filter or to bypass the filter. The valve includes a lever slidably connected to a valve stem by means of a pin fixably attached to the lever and extending through a slot of the stem. The slot is arranged relative to the longitudinal axis of the stem to lock the pin and lever in either the filtering position or the bypass position.
