Patent number: 5429424Abstract: A pneumatic brake system for use with an additional brake including a by-pass valve in parallel to a shut-off valve. The by-pass valve is opened only during an actuating or controlling of the pneumatic brake which exceeds a control range and opens up the passage through the brake pressure line irrespective of the switching condition of the shut-off valve. The connection of the brake cylinder line section of the brake pressure line with the atmosphere by the shut-off valve is at least choked when the by-pass valve is opened up.Type: GrantFiled: December 6, 1994Date of Patent: July 4, 1995Assignee: Knorr-Bremse AGInventors: Erich Huber, deceased, Robert Hofstetter, heir, Gortiz Bernd

Patent number: 5404758Abstract: A flowmeter for determining the amount of flowing medium using an orifice (4) and a resistor body (5) in a cavity (6) through which the medium to be measured flows. Not the resistor body (5) but an orifice sleeve (4) is displaced as a consequence of the varying primary pressure and thus the degree of opening of the flow orifice is determined depending on the amount of flow of the flowing medium. A satisfactory linearization of the subregion of the function .DELTA.p (V) is obtained.Type: GrantFiled: September 3, 1993Date of Patent: April 11, 1995Assignee: Knorr-Bremse AGInventors: Erich Huber, Gerhard Gasper

Patent number: 5328253Abstract: The electropneumatic control system for the pressure in the main air pipe (37) of compressed air brakes of rail cars is provided with one inlet and one outlet solenoid valve (3 and 4) to control the pressure in a control chamber (26) of a relay valve (19). The inlet solenoid valve (3) and the relay valve (19) are supplied with compressed air from a main reservoir pipe (34). The relay valve controlled by the pressure in the control chamber (26) against the pressure in the main air pipe (37) controls the compressed air lead-in and lead-out for the main air pipe (37). To avoid the undesired response of the relay valve (19) to pressure changes elsewhere in the main air pipe (37), the two sides of the piston (20) of the relay valve (19) are closed without any throttling by way of the secondary valve parts (13 or 14) of the two solenoid valves (3 and 4) in the unactuated state of the control system (2).Type: GrantFiled: September 27, 1993Date of Patent: July 12, 1994Assignee: Knorr-Bremse AGInventors: Bernd Goritz, Erich Huber

Patent number: 4714349Abstract: A photoelectric length or angle measuring system for measuring the relative position of two objects includes a graduation of a scale which is scanned by a scanning plate of a scanning unit. The scanning unit includes an illuminating unit for the illumination of the graduations of the scale and the scanning plate. In this illuminating unit there is arranged a light emitting diode on a surface of a carrier. For the improvement of the light radiating characteristics of the illuminating unit, reflections in the direction of the graduations of the scale and the scanning unit of light beams emerging laterally from the light emitting diode are avoided by properly configuring the surface of the carrier. In alternate embodiments, this surface of the carrier consists of a light absorbing material, is covered by a light absorbing material, or is provided with a dimension along the measuring direction no greater than that of the light emitting diode.Type: GrantFiled: July 23, 1984Date of Patent: December 22, 1987Assignee: Dr. Johannes Heidenhain GmbHInventor: Erich Huber

Patent number: 4463991Abstract: Release valve apparatus capable of being actuated by the vacuum that can be created in a main air line (1) for indirect air brakes of rail vehicles, comprising a release valve (12) in a connection (pipes 8, 9) from the brake control valve (3) to the brake cylinder (10). The release valve (12) contains a piston controlled two-way valve (24, 27, 28), which unblocks the passage in the off position of the release valve (12). In the actuated position, on the other hand, it blocks passage and vents the connecting segment (pipe 9) on the brake cylinder side. The piston (13) of the release valve (12) is loaded in the off position operating on a smaller piston area by main air line pressure, and by opposing pressure in an admission area (15) which is under atmospheric pressure in the off position and during the switching process to the operating position, and in this position is impacted by pressure in the connecting segment (pipe 8) leading to the brake control valve (3).Type: GrantFiled: March 7, 1983Date of Patent: August 7, 1984Assignee: Knorr-Bremse GmbHInventors: Erich Huber, Johann Huber
