    摘要： A fluid control device for use in a high pressure fluid system, the device including a device body with a cavity and a high pressure circuit, a plunger positioned for reciprocal movement in the cavity, and a leakage reduction cap mounted to the plunger for reducing fluid leakage flow. In one implementation, the leakage reduction cap includes a flexible portion positioned between the device body and the plunger, and defining an annular clearance gap between the leakage reduction cap and the device body. The flexible portion of the leakage reduction cap resiliently flexes radially outwardly in response to fluid pressure forces to reduce the annular clearance gap so as to minimize fluid leakage flow through the annular clearance gap.

    摘要： A wear resistant, reduced stress at increased injection pressure fuel distributor assembly for distributing high pressure fuel to the fuel injectors of an internal combustion engine is provided. The assembly includes a fuel distributor rotor with a surface profile configuration that effectively and efficiently distributes high and low pressure fuel to the fuel injectors without internal fuel distribution channels. The rotor is preferably formed from a high thermal expansion, wear-resistant ceramic or coated metal material.
