In order to provide a piston device that is of simple construction and provides optimised sealing, it is proposed that the piston device should include the following: a housing that includes a piston receptacle; a piston that is arranged to be linearly displaceable in the piston receptacle; a main gasket element that separates a first medium space from a second medium space, and a supplementary gasket element, different from the main gasket element, for sealing in a region between the piston and the piston receptacle.

Piston device and pump device

In order to provide a sealing element which ensures a reliable seal and which can be produced easily and economically, it is proposed that a main body of the sealing element is preferably formed from a partially fluorinated or fully fluorinated thermoplastic material and has obtained at least part of its final outer shape or only part of its final outer shape in particular in a high-pressure process and/or in a high-temperature process.

Sealing element and method for producing a sealing element

In order to provide a seal for sealing a sealing gap between a first component and a second component, comprising a seal body with at least one sealing portion and at least one spring element for biasing the sealing portion against at least one of the components to be sealed, the spring element being at least partially arranged in a receiving space of the seal body, which seal is simply constructed and easily producible and nevertheless ensures a secure retention of the spring element in the receiving space, it is proposed that the spring element has at least one claw element, by means of which the spring element is interlocked with the seal body.
