| 20100019068 | FUEL INJECTOR WITH AN INTEGRATED PRESSURE BOOSTER - Proposed is a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector has a housing in which are arranged an injection valve element with a nozzle needle, a pressure boosting device, and a first control valve, and a second control valve. The first control valve controls a control space of the nozzle needle and the second control valve controls a differential pressure space of the pressure boosting device. A first return flow connection is provided for discharging the control quantity of the control space of the nozzle needle, and a second return flow connection is provided for discharging the control quantity of the pressure boosting device. The two return flow connections are arranged on different housing parts of the housing. | 01-28-2010 |
| 20100163654 | Pneumatic Spray Gun - A hand-held spray gun has a fluid inlet, a nozzle, and a fluid flow path configured to communicate the inlet with the nozzle. A trigger valve opens and closes the flow path. Another valve has a valve body that varies a flow area in the flow path upon moving through a range of positions. A thumbwheel rotates the valve body, which moves through the range of positions by rotating about an axis while remaining stationary along the axis. Additionally, a nozzle assembly includes a base part and a cap part that varies a fluid spray pattern upon rotating about an axis relative to the base part. One of those parts has a projection. The other has a pair of circumferentially spaced-apart stop surfaces defining opposite ends of an arcuate path of movement for the projection when the cap part rotates about the axis. | 07-01-2010 |
| 20100288856 | MANUAL SPRAY PUMP - Disclosed herein is a hand-operated spray pump configured to discharge a predetermined amount of content upon pressing a button and to suction a residual portion of the content in an end of a nozzle after discharging the content, the hand-operated spray pump including a housing forming the external appearance of the pump, a housing cap configured to seal the internal space of the housing from the outside, the closure configured to mount a container containing content in the housing, the closure being integrally formed with the housing cap, a stem configured to move upward and downward while being connected to the lower end of the button, the shaft configured to move upward and downward along the inside of the housing cap while being coupled to the outside of the stem, a piston configured to move upward and downward along the inner wall of the housing, a compression spring provided between a side protrusion formed at the upper end of the shaft at the side of the shaft and the housing cap, an opening and closing member configured to move upward into and downward from the vertical channel through the lower end of the stem such that the residual content in the nozzle is suctioned after pumping, and a sealing member mounted at the lower end of the stem in a state in which the sealing member is in tight contact with the outside of the opening and closing member inserted into the vertical channel. | 11-18-2010 |
| 20130043331 | Staged Cooling Flow Nozzle Valve - A fuel split control arrangement is provided. The arrangement includes a staged cooling flow control valve and cooling check valve. The staged cooling flow control valve and cooling check valve is connected between the primary and secondary tips of a nozzle in a turbine engine. The staged cooling flow control valve and cooling check valve includes a valve member arrangement operable to prevent fuel flow from the secondary fuel supply manifold to the secondary tip and simultaneously allow fuel flow from the secondary fuel supply manifold to the primary tip such that the primary tip receives fuel flow from both the secondary fuel supply manifold and the primary fuel supply manifold. | 02-21-2013 |
