Abstract

See full text

A piston for dispensing a flowable component from a cartridge includes a piston having a base body and a venting element. The base body has a passage connecting a component side and an actuation side and has a passage opening. The venting element has an internal connection element and a pin which is partly arranged in the passage opening of the base body. The internal connection element and the pin are connected by a spring element. The pin of the venting element can adopt a sealing position and an aerating position. To enable a secure sealing, the spring element is configured such that it includes an angle of a maximum of 80° with the axial direction in the sealing position of the pin at a connection line to the internal connection element in the direction of an actuation side.
