  • Patent number: 4574826
    Abstract: A fill valve for controlling liquid level in a toilet water tank or other tank includes a valve head assembly positioned at a selected level in the tank by a telescoping riser assembly with liquid inlet and outlet conduits extending toward the tank bottom. An adjusting nut on a stationary riser engages thread structures on inlet and outlet conduits for raising or lowering the valve head assembly and adjusting the liquid level. A main valve in the head assembly is controlled by a non-horizontal diaphragm separating a vent chamber and a control chamber. The control chamber is pressurized as liquid rises to the selected level by a standpipe extending downwardly in the tank. The valve closing and opening levels are offset by partly filling the vent chamber with liquid when the main valve is open to hydraulically load the diaphragm. A vacuum breaker valve obstructs backflow through the valve, vents the flow path when the valve is closed, and regulates flow into the vent chamber when the valve is open.

  • Patent number: 4573495
    Abstract: A ballcock assembly having an upright standpipe for delivery of flush water, a control valve assembly at the upper end of the standpipe, and a float and ballast assembly slidably mounted for up and down movement relative to the standpipe and connected to the control valve assembly. The control valve assembly operates to open the valve to flow of flush water from the standpipe assembly in response to downward movement of the float and ballast assembly. When the float assembly is caused to rise by incoming flush water from the standpipe, it ultimately causes the control valve to shut off incoming flow of flush water from the standpipe.

  • Patent number: 4562858
    Abstract: A stepper for use between a transducer subjected to variable pressure, heat or liquid level for converting the continuous output signal of the transducer with all of its variations, both of significant magnitude and those of insignificant importance, into a continuous stepped output signal that increases or decreases the current to a transducer responsive control unit, particularly a servo amplifier, which stepped signal eliminates all minor and unimportant fluctuations from the output current from the transducer. The stepper also includes a sequence of voltage regulators such as potentiometers in the circuits between the stepper and the servo amplifier by means of which the magnitude of the current flow of each step to the servo amplifier may be adjusted or programmed with respect to one another. It is particularly useful in the regulation of flow control valves in water distribution and sewage disposal systems, but its application to steam boilers is also disclosed and described.

  • Patent number: 4482127
    Abstract: A valve of the type which is actuated under the pressure of the medium it controls and in which axially-aligned actuating and damping pistons are disposed within cylindrical relief and damping chambers and are connected to a valve element engageable with a valve seat disposed between inlet and outlet valve ports. The actuating piston acts under the pressure of the medium it controls to actuate the valve element in response to a reduction in pressure in the relief chamber. The invention itself resides in the provision of a restricted passageway which interconnects the relief and damping chambers whereby the pressure in the damping chamber will be reduced slowly in response to a reduction in pressure in the relief chamber whereby, if the valve should stick or otherwise become slow-acting, the pressure within the damping chamber will assist and insure that the valve is actuated even though it may not be in the best operating condition.

  • Patent number: 4406121
    Abstract: A multiple stage energized fluiel flywheel is contained within a housing. An axially extending shaft is rotatably mounted within the housing. Fluid is introduced into the unit through an initial axial flow section and further pressure increases are experienced in a radial blower section and an annular squirrel cage section peripherally arranged about the radial blower. Pressurized fluid discharged from the squirrel cages is directed to either a peripheral exhaust ring which discharges pressurized fluid to the reservoir interior or to an adjacent hydraulic motor. The hydraulic motor includes a rotor which is secured to the stator section of the initial axial pumping section. The axial shaft, radial blower, squirrel cage and exhaust section rotate as a unit in one direction of operation. The hydraulic motor and axial pumping section stator rotate as a unit in the opposite direction of rotation. The flywheel may operate using air, hydraulic fluid or other motive fluids.
