摘要： A novel and improved motion sensor for high pressure fluid delivery devices is provided which effectively senses movement of a component in a high pressure environment while minimizing the likelihood of fluid leakage through a receiving cavity containing at least a portion of the sensor. The motion sensor includes a sealing surface shaped and positioned relative to a force resisting surface formed on an annular cavity surface of the receiving cavity so as to apply a fluid, e.g. fuel, pressure induced sealing force against the force resisting surface due to the high pressure fluid forces acting on the sensor body. The sealing surface may be conically shaped for contacting a complementary conically shaped force resisting surface and/or the sealing surface may extend perpendicular to the direction of the fluid forces acting on the sensor body for abutment against a complementary positioned annular land containing the force resisting surface.
