Publication number: 20140261330Abstract: A fuel rail assembly configured for connection to an internal combustion engine includes a first fuel rail, a second fuel rail, and a crossover hose. The first fuel rail includes an inlet having a first flow restrictor and configured to be coupled to a high-pressure pump. The first fuel rail further includes a second flow restrictor disposed in an interior portion that divides the interior into a first rail volume and a remainder volume. The crossover hose includes a third flow restrictor near the end that is connected to the second fuel rail. A first pulsation control volume is defined between the pump and the inlet. A second pulsation control volume is defined to include the remainder volume and the volume in the crossover hose (i.e., between the first and second flow restrictors). The pulsation control volumes reduce pressure fluctuations produced by the high-pressure pump.Type: ApplicationFiled: March 11, 2014Publication date: September 18, 2014Inventor: Robert J. Doherty

Patent number: 5120915Abstract: A pressure switch according to the invention combines a pressure chamber with diaphragm, plunger, spring-loaded switch mechanism and electrical contacts in a single compact assembly. According to one aspect of the invention, the terminal board of the pump motor is incorporated into the control switch housing, eliminating the need for wiring from the switch to the terminal board and enabling the switch to be mounted inside the wiring compartment of the motor. According to another aspect of the invention, a pair of opposing blades are used in the switch mechanism to eliminate side forces and decrease friction, improving accuracy and life of the switch. A simple set screw may be used with one of the switch blades, in cooperation with a stop associated with the other blade, to adjust the spring force and thereby control the pressure control differential.Type: GrantFiled: February 1, 1991Date of Patent: June 9, 1992Assignee: Johnson Service CompanyInventor: Robert J.
