    • An exemplary pump includes a pump housing defining a pump cavity, a movable pumping member situated in the pump cavity, and at least one pressure-absorbing member located inside the pump housing. The housing also has an inlet and an outlet, and includes at least one interior non-wearing location that contacts liquid in the pump housing when the pump housing is primed with the liquid. The movable pumping member, when driven to move, urges flow of the liquid from the inlet through the pump cavity to the outlet. The at least one pressure-absorbing member is located inside the pump housing at the non-wearing location and contacts the liquid. The pressure-absorbing member has a compliant property to exhibit a volumetric compression when subjected to a pressure increase in the liquid contacting the pressure-absorbing member, the volumetric compression being sufficient to alleviate at least a portion of the pressure increase.
    • 示例性泵包括限定泵腔的泵壳体,位于泵腔中的可移动泵送构件以及位于泵壳体内部的至少一个压力吸收构件。 壳体还具有入口和出口,并且当泵壳体被液体注入时,该入口和出口包括至少一个内部非易磨损位置,该位置接触泵壳体中的液体。 可移动泵送构件当被驱动移动时,促使液体从入口通过泵腔流到出口。 所述至少一个压力吸收构件位于所述泵壳体内的所述非磨损位置处并接触所述液体。 压力吸收构件具有柔软性,以在与压力吸收构件接触的液体中受到压力升高时呈现体积压缩,体积压缩足以减轻至少一部分压力增加。

    • PURPOSE: A hydraulic unit is provided to reduce noise and pulsation of pressure from a pump by using a damping unit, and to cut down cost by securely sealing the inlet of the damping unit in assembling the pump without additional sealing materials. CONSTITUTION: A hydraulic unit for a brake system electronically controlled of a vehicle is composed of a housing block(10), and the housing block is composed of an installation surface(12) for the electronic control unit, a hydraulic connection space supplying pressure media to the hydraulic unit, an installation space(24) for a pump(50) and a damping unit(22). The damping unit is arranged in the lower part of the pump to damp pulsation of pressure and to regulate brake pressure of a wheel brake cylinder. The installation space of the damping unit and the installation space of the valve are extended to the installation surface of the housing block, and the damping unit is protruded on the installation surface.
