Title:
LIP SEALING PIECE
Document Type and Number:
Japanese Patent JPS5761863
Kind Code:
A
Abstract:
A lip seal of elastic material has at least one sealing lip having a knife-edge sealing ridge particularly for sealing an axially moving part of a device from a liquid space, for instance in a galvanic metal-air cell. In order to improve the sealing of the axially moving device part with respect to the liquid space and to lengthen the sealing action, a membrane-like protective lip is formed on the liquid side in front of the sealing ridge, the lip resting with areal contact against the device part which is to be sealed off. The membrane-like protective lip due to its inherent tension or initial tension applies itself with high unit surface pressure against the surface of the device part to be sealed off.
