Abstract (en)

[origin: WO2007140869A1] The invention relates to a hydrostatic piston machine having a housing (2), a cylinder drum (3) which is mounted rotatably in the latter, a multiple disc brake (16) and a thrust ring (21) for this purpose. The cylinder drum (3) can be braked in the housing (2) by the multiple disc brake (16), the multiple disc brake (16) comprising at least one first brake disc (19) which is connected fixedly in terms of rotation to the cylinder drum (3) and at least one second brake disc (20) which is connected fixedly in terms of rotation to the housing (2). The brake discs (19, 20) can be pressed onto one another by the thrust ring (21), the thrust ring (21) being a plastic ring and having at least one region (35, 36) which is elastic in the radial direction and on which a sealing element is provided.
