摘要： The invention relates to a pump element for installation in a pump bore of a hydraulic block, which includes a pump plunger, a restoring spring for the pump plunger, and an inlet valve having an inlet valve cover, in which a closing spring and a closing body are arranged. According to the invention, the inlet valve cover has a high pressure sealing section, which rests against the valve seat element in the axial direction with spring force support provided by the restoring spring. The valve seat element is positively connected to the pump plunger at least before installation of the pump element in the pump bore. Centering elements are provided for centering the inlet valve cover relative to the valve seat element. The invention further relates to a hydraulic block and to an installation method.
