20090000605 | Regeneration system having integral purge and ignition device - A regeneration device is disclosed. The regeneration device has an injector configured to inject pressurized fuel during an injection event. The regeneration device also has a heater configured to ignite the pressurized fuel during the injection event. The heater is also configured to purge the injector between injection events. | 01-01-2009 |
20140127036 | PLUNGER WITH OUTLET VALVE ASSEMBLY FOR PLUNGER PUMPS - A plunger pump includes a housing with a discharge valve in communication with an outlet. The housing includes a bore that slidably accommodates a plunger. The housing also includes an inlet. The plunger has a closed proximal end connected to an actuator and a distal end with an outlet valve. The plunger also includes a sidewall with an opening that is in communication with the inlet of the housing. Fluid flows through the inlet and through the opening and into the plunger. When the plunger is retracted away from the discharge valve, the outlet valve of the plunger opens thereby providing fluid for the housing bore. As the plunger is moved towards the discharge valve, pressure in the housing bore increases thereby opening the discharge valve and permitting the pressurized fluid to exit through the outlet. | 05-08-2014 |
