Abstract
The invention relates to a housing block into which a piston pump is inserted. For sealing off and fixing a cylinder of the piston pump in the housing block, the cylinder is provided with a radially outward-protruding annular shoulder, which when the cylinder is press-fitted in the housing block displaces material of the housing block and deforms the housing block plastically radially inward until material rests sealingly on the cylinder and fixes the cylinder in the housing block. The invention makes it possible to accomplish securing and sealing in one operation in an economical way, without requiring additional securing means and economizing on one high-pressure-proof sealing ring.
