Patent number: 8011483Abstract: A ventilation device provided which includes a valve arranged in a combined spring accumulator and operating brake cylinder. On depressurization of a pressure medium chamber in the spring accumulator brake cylinder, ventilation of a spring accumulator chamber of the spring accumulator brake cylinder, from the pressure medium chamber of the operating brake cylinder, is effected. A chambers is provided on the side of a valve piston in the valve, facing away from a control chamber, which, with an open valve, connects a first working connections to this chamber and, hence, to a second working connection, arranged axially on the front side of the valve, by means of a passage provided in the valve piston.Type: GrantFiled: November 11, 2005Date of Patent: September 6, 2011Assignee: WABCO GmbHInventors: Oliver Brandt, Wilfried Matthias, Andreas Richter

Publication number: 20100192767Abstract: The invention relates to a method for mounting a fastener screw (2, 3) on the base (5) of a brake cylinder (1). The method comprises the following steps: first, producing bores (8) in the base (5) of the brake cylinder (1) that have a smaller diameter than the diameter of the fastener screw (2, 3). Subsequently, the bore (8) is widened using a stamping tool (9) far enough that the fastener screw (2, 3) will fit through said bore, forming a collar (11). Finally, the collar (11) is reformed onto the fastener screw (2, 3) by a pressing process, whereby said collar engages in a groove (12) or a ribbing (15) of the fastener screw (2, 3), thus securing said screw.Type: ApplicationFiled: June 30, 2008Publication date: August 5, 2010Inventors: Oliver Brandt, Jürgen Ewald, Wilfried Mathias, Frank Schrader, Oktawian Szuberski

Publication number: 20090032456Abstract: A device for filtering a fluid, in particular a liquefied plastic, has a housing with at least one supply channel and having a discharge channel. In the flow path of the fluid at least one screen is arranged in a corresponding screen space in at least one screen carrier, which is supported so as to be displaceable crosswise to the direction of flow. The screen can be brought into connection with the supply channel and with the discharge channel, the screen being formed as an elongate oval or a polygon. The channel splits into two partial supply channels, which open out into the screen space on the dirty side of the screen. The front supply channel, viewed in the screen change direction, opens out into a channel worked into the screen carrier, which channel feeds to the screen space the plastic to be filtered.Type: ApplicationFiled: July 16, 2008Publication date: February 5, 2009Applicant: Kreyenborg Verwaltungen und Beteiligungen GmbH & Co.
