Abstract:
A fluid leak limiter for a high-pressure fuel injection system is disclosed. The fluid leak limiter may have a body at least partially defining a central bore with a fluid inlet and a fluid outlet, and a sleeve piston. The fluid leak limiter may also have a spring located to bias the sleeve piston toward a first flow-blocking position. The sleeve piston may be movable by a first pressure differential between the fluid inlet and the fluid outlet against the bias of the spring toward a flow-passing position at which fluid from the fluid inlet is allowed to flow to the fluid outlet. The sleeve piston may also be movable by a second pressure differential between the fluid inlet and the fluid outlet against the bias of the spring toward a second flow-blocking position at which fluid from the fluid inlet is inhibited from flowing to the fluid outlet.
