  • Patent number: 10035168
    Abstract: A base valve, a base pump, a catalyst valve, a catalyst pump, a mixing chamber, a base cylinder connected to the base valve, and a catalyst cylinder connected to the catalyst valve. The base and catalyst cylinders are actuated so as to push base and catalyst fluids out of the base and catalyst cylinders, respectively, and into the mixing chamber. An electronic controller has a ready mode and a dispensing mode. In the ready mode, the controller i) activates the base and catalyst pumps and ii) signals the actuator to push or pull, in response to a dispense signal being asserted. In the dispensing mode, the controller a) deactivates the base and catalyst pumps, b) signals the actuator to stop pushing or stop pulling, and maintains a) and b) in response to the dispense signal being de-asserted. Other embodiments are also described.

  • Patent number: 6767190
    Abstract: Methods and apparatus for electrostatically pumping fluids without passing the fluids through the electric field of the pump are contemplated. Electrostatic forces are preferably used to move the diaphragms in one direction, while elastic and/or other restorative forces are used to move the diaphragms back to their original un-activated positions. In some embodiments, this may allow fluid to be pumped without passing the fluid between actuating electrodes. This may be particularly useful when the fluids have dielectric, conductive, polar or other qualities that may affect traditional electrostatic pump performance. Pumps having various elementary cells are contemplated, including two-celled pumps disposed within a single chamber and pumps having greater numbers of cells wherein each cell is disposed within a different chamber.

  • Patent number: 5997259
    Abstract: An electronically controlled diesel engine for a vehicle which may act as an air compressor in addition to acting as a power source for the vehicle. When acting in the air compressor function, one end cylinder is converted to the function to provide compressed air to air tanks on the vehicle. The air from this combination compressor and power cylinder may be used to fill air tanks which provide air for braking in vehicles such as heavy trucks. The combination compressor and power cylinder has an exhaust isolation valve in the exhaust manifold to isolate an air collection area and a relief/check valve engaged on an upstream side to the air collection area and to an air tank in the air system for the vehicle on the downstream side. An electronic controller means controls the fuel injector for the combination compressor and power cylinder and the exhaust isolation valve. Various types of diesel engines may be modified to become an electronic engine-air compressor system in accordance with this invention.

  • Patent number: 4836198
    Abstract: A portable ventilating device for ventilating patients in the field. A reciprocating piston divides a cylinder into a pressure chamber and a spring chamber in which a compression spring acts against the piston. Gas pressure applied to the pressure chamber opposes the spring force and reciprocates the piston. As the piston reciprocates ventilating gas is forced out of the piston chamber through a ventilation line equipped with a check valve. Alternative embodiments provide gas pressure assistance to the spring, make use of the gas which powers the device as the ventilating gas, and provide adjustment of the duration for the time periods gas is applied to the cylinder.

    Abstract: A casting system for the processing of casting resin. From evacuatable storage containers casting resin components are fed to pump cylinders. The movement of the pump cylinders is synchronized through a mechanical connection. The drive of the pistons in the pump cylinders occurs by means of driving fluids which approximately are under the same pressure as the resin components. Leakages across the pistons are avoided due to the pressure equality on both sides of the pistons even when, in consideration of abrasive filler materials, relatively large gaps must be provided between the pistons and their cylinders.

  • Patent number: 4494913
    Abstract: A positive displacement injector for automatic centralized lubrication systems is constructed to include a two-piece disk-seal valve assembly that acts as a check valve and also provides seals at oppositely facing surfaces. The assembly consists of a stiff disk sandwiched between upstream and downstream disks of a resilient seal member. Notches in the periphery of the stiff disk are normally blocked by the downstream disk to prevent upstream fluid flow through these notches, yet the periphery of the downstream disk is deflectable to permit downstream fluid flow through the notches when there is relatively high fluid pressure at the inlet port. The assembly is bodily movable so that with low fluid pressure at the inlet port this port is blocked by the upstream disk, and with high fluid pressure at the inlet port the downstream disk blocks axial input to an outlet passage.

    Abstract: A spring actuated piston pump for use in lubricating the bearings of a turbo-charger rotor, both on starting and stopping an associated internal combustion engine. The pump has a piston-and cylinder combination the piston of which is spring-urged towards the cylinder head, and there is a releasable catch arrangement operable on the piston to restrain movement of the piston towards the cylinder head when the piston is part-way between the extremes of its travel. The catch means is solenoid operated for connection to the engine starter system, so that the piston is released when the engine is started.The pump chamber is connected to the engine lubrication system and the turbo-charger bearings through suitable ducts and one-way valves, so that on ordinary operation of the engine the pump chamber is full of oil with the piston fully retracted. On stopping the engine the piston moves under the spring bias discharging oil to the turbo-charger bearings until restrained by the catch arrangement.
