Cylinder piston for an air compressor

A cylinder piston for an air compressor, comprising:

• a piston surface having at least two channel openings integrated therein, the at least two channel openings forming at least one inlet valve and at least one outlet valve respectively;
• a coherent, one-piece and flexible bending sealing element provided inside or covering the at least two channel openings, the sealing element enabling an inflow into at least one of the channel openings or an outflow from at least one of the channel openings;
• wherein the at least two channel openings being designed independently of one another as an inlet valve or as an outlet valve, by the flexible bending sealing element,
• wherein the flexible bending sealing element is fixed to the piston surface of the cylinder piston via a retaining plate in such a way that a closing or opening movement of the flexible bending sealing element in a region of the respective at least two channel openings is made possible, and
• wherein the retaining plate has a respective recess in the region of each of the at least two channel openings, to provide the at least one inlet valve and the at least one outlet valve, the respective recesses having a different diameter to form a diameter of an inlet opening of the at least one inlet valve or a diameter of a stop ring of the at least one outlet valve, and
• wherein
• the diameter of the respective recess is larger than the diameter of the respective channel opening and the sealing element is configured to be deflected through the recess in the direction of the retaining plate to provide the at least one inlet valve, and
• the diameter of the respective recess is smaller than the diameter of the respective channel opening and the sealing element is configured to seal the channel opening by deflecting it in the direction of the retaining plate to provide the at least one outlet valve.
