Abstract: A gimbal tube system for an onboard injector (OBI) includes a transfer tube having a first transfer tube end that can be mounted to an inner diameter of a stator platform and a second transfer tube end defining a transfer tube pivot connector. The system also includes a gimbal tube including a first gimbal tube end that defines a gimbal tube pivot connector that can movably mount to the transfer tube pivot connector such that the gimbal tube and the transfer tube can move relative to each other at a pivot joint defined between the transfer tube and the gimbal tube. The gimbal tube further includes a second gimbal tube end defining a nozzle that can be inserted into the OBI.

Abstract: A valve assembly including a valve body having a bore and a port extending to the bore, an orifice member received in the bore and having an end wall and a side wall, and wherein the end wall defines an orifice providing fluid communication with the port of the body. A valve member is received in the orifice member and is movable along an axis with respect to the orifice, and a flat spring is secured to the side wall of the orifice member and has arms secured to the valve member. A valve seat is secured to the end wall and defines an opening over the orifice, and a plug is secured to an end of the valve member opposite the valve seat such that, when the valve member is moved along the axis towards the orifice, the plug contacts the seat to seal the opening.

Abstract: A valve assembly including a body having an inlet port, an outlet port, and a valve seat having a passageway. An electrical solenoid assembly moves a valve member upon being energized to control fluid flow between the inlet and the outlet ports. The valve assembly also includes a fluid-tight bellows positioned to apply a force to the valve member, and a pressure balancing passageway connects the inlet port to the bellows. The valve assembly further includes a housing received over the solenoid assembly and having a flange received against the valve body. A seal is positioned between the flange of the housing and the valve body, and a collar is secured in a continuous manner to the valve body over the housing flange, thereby securing the housing to the valve body and applying a sealing force to the seal in a substantially even manner.
