摘要： The invention relates to a piston pump for a slip-controlled hydraulic vehicle brake system. To make a piston of the piston pump easy and inexpensive to manufacture, the invention proposes that the piston be comprised of a sleeve-like shaped part and a valve seat part that is made of plastic and is press-fitted into the shaped part. A high-pressure-side sealing lip is formed onto the valve seat part and is of one piece with it. By means of a tubular support body, a restoring spring is supported on the valve seat part spaced apart from a valve seat of the valve seat part and spaced apart from the sealing lip, which prevents the valve seat and the sealing lip from being impaired by the force of the restoring spring.

摘要： The invention relates to a check valve with a tubular valve housing in which a valve ball is received. To make a large flow cross section available and to prevent closure by the valve ball when the check valve is fully open, a perforated disk is press-fitted between longitudinally extending guide ribs of the valve housing and a circumferential wall of the valve housing there is an interstice as an outflow opening, which is not closed even the valve ball contacts the perforated disk. The valve housing is made by stamping, in which the guide ribs and a valve seat are made in one operation and are thereby aligned exactly with one another. In this way, a small radial play of the valve ball can be realized.
