Abstract:
A pressure limiting valve for a fuel injection system may include a sleeve, a fixing pin, a spring, a sealing element, and a seat. The sleeve may have a longitudinal axis. The fixing pin protruding through a cavity enclosed by the sleeve. The spring may have a first end supported on the sleeve and a second end supported by the sealing element. The seat may provide a sealing surface for the sealing element to block a fluid flow through the valve when closed position, and allow this flow to pass in other positions. The outer circumference of the sleeve may vary within predefined tolerances along the longitudinal axis. The fixing pin may be shaped to plastically deform by a movement of the fixing pin along the longitudinal axis, in order to press the sleeve into the housing.
