Patent number: 9879660Abstract: A pump moves fluid by a piston reciprocating inside a cylinder. Fluid enters the cylinder through an inlet valve that passes through the cylinder head, and has an enlarged surface inside the cylinder, which seals against the cylinder head. This valve is normally held closed by a spring. As the piston advances, fluid is forced out of the cylinder through a passage in the cylinder head and a check valve. A rod is affixed to the piston and passes through the inlet valve. As the piston retracts, the rod slides through the inlet valve, until a stop, affixed to the rod, encounters the stem of the inlet valve. The spring holding the valve closed is overcome and the valve opens as the piston and rod move farther, until the piston is in its fully retracted position. Fluid enters the cylinder until the piston again begins to advance. The stop ceases to push the inlet valve open, and the spring again holds it closed.Type: GrantFiled: June 20, 2015Date of Patent: January 30, 2018Assignee: Springboard Biodiesel, LLCInventor: Galen Michael Bowen

Patent number: 9879661Abstract: A vibrational fluid mover assembly having an active damping mechanism is disclosed. The vibrational fluid mover assembly includes a vibrational fluid mover having a first plate, a second plate spaced apart from the first plate, a spacer element having an orifice formed therein and being positioned between the first and second plates to maintain the first and second plates in a spaced apart relationship, and an actuator element coupled to at least one of the first and second plates to selectively cause deflection thereof such that a fluid flow is generated and projected out from the orifice. The vibrational fluid mover assembly also includes an absorber system connected to the vibrational fluid mover and providing active damping to the vibrational fluid mover, with the absorber system having suspension tabs coupled to the vibrational fluid mover and spring components configured to mount the vibrational fluid mover in a suspended arrangement.Type: GrantFiled: August 29, 2014Date of Patent: January 30, 2018Assignee: General Electric CompanyInventors: Gamal Refai-Ahmed, John Anthony Vogel, Christian M.

Patent number: 9879663Abstract: A multi-phase pump system and method that directs incoming two-phase flow into a fixed cylinder that contains a vortical flow. The system includes a momentum-driven, vortex phase separator, the phase separator accepting liquid-gas flows at any ratio from all liquid to all gas. The pump system also includes a liquid prime mover; a gas prime mover; and a control system. The vortical flow is driven by injecting the two-phase or another fluid stream tangent or approximately tangent to the curved surface of the cylindrical chamber. Inertial forces generated within the vortical flow drive a buoyancy-driven separation process within the cylindrical chamber. Single-phase prime movers are then used to pump the separated phases to a higher pressure.Type: GrantFiled: March 1, 2013Date of Patent: January 30, 2018Assignee: Advanced Cooling Technologies, Inc.Inventor: Michael C.

Patent number: 9879665Abstract: A portable electric inflator includes an electric air compressor, a pressure gauge, and a box for accommodating the electric air compressor and the pressure gauge. The box defines therein a generally L-shaped space for accommodating a cooling fan, a motor, a main frame with a transmission mechanism, a cylinder with a piston body, and an air storage tank of the electric air compressor. The motor defines two openings at its surrounding wall and multiple downstream through holes at its bottom wall. The main frame is provided with a peripheral wall and beveled radial braces and defines two through holes to facilitate the airflow passing through the main frame. The cooling fan can draw outside air to enter the box and smoothly flow along the generally L-shaped space to quickly dissipate the heat generated by the electric air compressor, whereby the performance and safety of the inflator can be increased.Type: GrantFiled: May 12, 2015Date of Patent: January 30, 2018Inventor: Wen-San Chou

Patent number: 9879666Abstract: A motor-driven compressor includes a compression mechanism compressing refrigerant gas, an electric motor driving the compression mechanism, a housing made of a thermally conductive material and accommodating the compression mechanism and the electric motor and an inverter assembly controlling rotation of the electric motor. The inverter assembly includes an elastic member made of a thermally conductive material and disposed in contact with the housing, a circuit board supported directly by the elastic member, an electronic part mounted on the circuit board and a base member made of a thermally conductive material, fixed to the housing and having a closed end. The base member fixes the electronic part. The base member and the housing cooperate to form an accommodation space that accommodates the elastic member, the circuit board and the electronic part. The closed end of the base member and the elastic member forms therebetween a space.Type: GrantFiled: October 16, 2012Date of Patent: January 30, 2018Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Ken Suitou, Yusuke Kinoshita, Tsuyoshi Yamaguchi
