Abstract: A high-pressure fuel supply pump for a fuel system that supplies a high-pressure fuel injection (GDI) apparatus and a low-pressure fuel injection (PFI) apparatus incorporates an inlet check valve to isolate a low-pressure fuel feed channel in the pump from pressure fluctuations at the inlet of an inlet control valve. Upstream of the inlet check valve, the low-pressure fuel feed channel is connected to a seal chamber surrounding the pumping plunger. Circulating fresh low-pressure fuel through the seal chamber ensures that the pumping plunger and the clearance between the plunger and the pump bore are cooled and lubricated with fuel, even when high pressure fuel is not produced by the high-pressure pump. The low-pressure fuel feed channel is connected to the low-pressure PFI outlet downstream of the seal chamber. This pump configuration provides stable source of low-pressure fuel for a PFI system.

Abstract: A dosing valve assembly is disclosed for administering a reducing agent into an exhaust stream within an exhaust manifold of an internal combustion engine. The dosing valve assembly comprises a control valve coupled to a source of the reducing agent, a reducing agent delivery valve constructed and arranged for coupling to the exhaust manifold to enable a specified quantity of reducing agent to be administered into the exhaust stream, and an elongated conduit disposed between the control valve and reducing agent delivery valve for fluidly communicating reducing agent from the control valve to the reducing agent delivery valve. The disclosed arrangement enables the reducing agent delivery valve to be coupled to the exhaust manifold and the control valve to be displaced from the reducing agent delivery valve and away from the high temperature environment associated with the exhaust manifold.

Abstract: The present invention provides a pivoting golf tee. The golf tee comprises an upper member and a lower member. The upper member provides a surface on which the golf ball rests and a lower member provides a pointed end such that the tee can be inserted into the ground. Between the upper and lower member is a snap together pivot. The upper member comprises of a socket that accepts the ball section of the lower member. Both the upper and lower members have a corresponding flat on the ball section such that when the two members are not axially aligned stress is applied between the two members. The corresponding stress is the mechanism that snaps the golf tee back to its coaxial position. A slot in the upper member adjacent to the socket provides a means by which the two members can be snapped together during initial assembly.
