  • Patent number: 8734132
    Abstract: The present invention addresses the need for a water pump that may be constructed from inexpensive materials available even in impoverished areas. The pump uses a simple rocking motion to pump water and can pump significant amounts of water from sources that otherwise could not be reached. In a preferred embodiment, the pump comprises three concrete chambers, a pumping platform adapted to rock in a see-saw fashion, and a plurality of valves to control the flow of water. The first two chambers contain diaphragms that, as a result of rocking the pumping platform, draw liquid into the chambers and force liquid from those chambers into the third chamber. Two valves selectively permit liquid to be drawn into the first and second chambers, and prevent the liquid from exiting the chambers and returning to the source. Third and fourth valves allow liquid to flow from the first and second chambers into the third chamber, and prevent the liquid in the third chamber from flowing back into the first or second chambers.

  • Publication number: 20130052052
    Abstract: An inflating pump with auxiliary knotting functions for filling up air balloons has a cylinder, piston, actuating shaft, operating handle and outlet nozzle. The piston is set slidably into the actuating space of the cylinder. The inner end of the actuating shaft is linked to the piston, and the outer end protruded from one end of the cylinder. The operating handle is linked to the outer end of the actuating shaft. The outlet nozzle is set to connect with the actuating space of the cylinder. An auxiliary knotting portion is set with a spacing to the outlet nozzle and has a bulge and an internal flange formed at end of the bulge for knotting purposes. After the air balloon is filled up with air, the user could rewind the opening of the air balloon for auxiliary knotting by taking the bulge and internal flange as the guiding structure.

  • Publication number: 20120230845
    Abstract: A pump drive and a method thereof to dispense a liquid drug from a container having a plunger piston are disclosed. The pump drive provides a unidirectional clutch provided about a rotational axis which supports centrally a wheel. The clutch has an inner race operably connected to the plunger piston, wherein the clutch is configured to rotate both the inner race about the axis in unison with rotation of the wheel in only a first direction to advance the plunger piston, and to let the wheel rotate relative to the inner race about the axis in a second direction opposite to the first direction without advancing the piston plunger. The drive in one embodiment includes at least one shape memory alloy wire which when excited rotates the wheel in the first rotational direction to advance the piston plunger and dispense the liquid drug from the container.

  • Patent number: 8186967
    Abstract: A fail-safe control method for an oil pump control unit of a hybrid vehicle directly connects an automatic transmission control unit and an oil pump control unit via a hard wire to control an oil pump driver in the event of a failure of the CAN communication line of the oil pump control. It enables the rotation speed of a motor of the electric oil pump to be controlled by a motor control unit (MCU) or a underdrive brake (UD_BRAKE) to be controlled in on/off mode or in slip mode by the automatic transmission control unit until a mechanical oil pump is driven, in the event of a failure of the oil pump control unit or the electric oil pump.

  • Patent number: 8182235
    Abstract: A multi-drive pump may include a pump housing, an inlet port, an outlet port, a primary pump gear, a secondary pump gear, a first internal mechanical drive mechanism coupled to the primary pump gear and a second internal mechanical drive mechanism and an internal electro-magnetic drive mechanism coupled to the secondary pump gear. The pump housing may define an internal volume fluidly coupled to the inlet port and the outlet port. The primary pump gear and the secondary pump gear may be positioned in the pump housing and coupled to one another. Rotation of the primary pump gear and the secondary pump gear draws fluid into the inlet port and expels fluid from the outlet port. The primary pump gear may be rotated by the first internal mechanical drive mechanism and the secondary pump gear may be rotated by the second internal mechanical drive mechanism and the internal electro-magnetic drive mechanism.

  • Patent number: 8181829
    Abstract: A suction and dispensing tool (1) comprises: a cylinder (10) storing the fluid; a nozzle (20); a piston moving forward and backward in the cylinder (10); a piston rod (40) for driving the piston; and two ratchet type driving mechanisms (60) for driving the piston rod (40) forward and backward. The driving mechanism (60) comprises: a frame (50) having a handle (52), mounted to the cylinder (10), and two triggers (80) rotatably attached to the frame (50) at the front and rear sides of the handle (52). By rotating each of the triggers (80) to the handle (52), the piston rod (40) can be moved forward or backward. The rotating operation of the trigger (80) requires power smaller than an operation for directly pushing and drawing the piston rod by hand. Accordingly, it becomes possible to refill and dispense a high viscosity oil easily.
