Patent number: 10933856Abstract: An electropneumatic pilot unit for controlling a pneumatic consumer is provided herein. The pilot unit comprises at least two electromagnetic pilot valves. Each of the electromagnetic pilot valves comprises a coil for producing a magnetic flux along a valve axis, an armature which can be moved in the axial direction of the valve axis, a valve seat which can be closed and opened by the armature, and a pneumatic inlet port and a pneumatic outlet port. At least two of the pilot valves lie next to each other with parallel valve axes. Each pilot valve has a port which protrudes towards a common underside for connection to a pilot chamber of the consumer controlled by the pilot valves.Type: GrantFiled: June 20, 2017Date of Patent: March 2, 2021Assignee: WABCO EUROPE BVBAInventors: Lars Didwiszus, Karsten Runge, Hartmut Schappler, Andreas Teichmann, Ingo Torhoff

Patent number: 10214191Abstract: A valve unit (1, 1?) for modulating the pressure in a pneumatic brake system, has a brake pressure inlet (3), a brake pressure outlet (4) and a venting outlet (5), a pneumatically controllable main valve (6, 7) and a pilot valve (8, 9), embodied as a solenoid valve and assigned to the main valve (6, 7), which are arranged in a valve housing (2, 2?) subdivided by a plane of division (10), into a main housing (11, 11?) and a housing cover (12). For fixing the housing cover (12) on the main housing (11, 11?) a bracket element (62.1) is fixed to the main housing (11, 11?) and bears with a largely planar pressure plate (63) generating an elastic prestressing force on a planar outside wall (64) of the housing cover (12) oriented parallel to the plane of division (10) of the valve housing (2, 2?).Type: GrantFiled: August 6, 2015Date of Patent: February 26, 2019Assignee: WABCO GmbHInventors: Werner Dreyer, Karsten Runge, Andreas Teichmann

Patent number: 10112590Abstract: A valve unit (1) for modulating pressure in a compressed air braking system includes a brake pressure input (3), a brake pressure output (4), and a purge output (5), an inlet valve (6) and an outlet valve (7), both configured as a diaphragm valve, and respective precontrol valves (8, 9), which are each configured as a 3/2-way solenoid valve. For effective sound damping of the compressed air emerging into the environment when the outlet valve (7) is open, the valve unit (1) at the purge output (5) has a silencer (75) with a largely cylindrical silencer housing (76) with an inlet opening (77), a calming chamber (78), a large outlet opening (79) and a silencer insert (80.1) arranged upstream of the outlet opening (79) inside the silencer housing (76). The silencer is air-permeable and sound-deadening and attached to the base housing (11) with base walls (83, 84).Type: GrantFiled: August 6, 2015Date of Patent: October 30, 2018Assignee: WABCO GmbHInventors: Stefan Klik, Karsten Runge, Andreas Teichmann

Patent number: 10011253Abstract: A valve unit (1.1, 1.2, 1.3) for modulating pressure in a compressed air braking system has an inlet valve (6) configured as a diaphragm valve, an outlet valve (7) configured as a diaphragm valve, and respective precontrol valves (8, 9), which are each configured as a 3/2-way solenoid valve and are arranged in an elongate valve housing (2), which is divided by a division plane (10) that is largely horizontal in the installation position into a base housing (11) and a housing cover (12). The precontrol valves (8, 9) are arranged in the housing cover (12) in the longitudinal direction (13), and the housing cover (12) has a centrally arranged magnet module (20) and two air guide modules (23, 24) adjacent to the magnet module (20) in the longitudinal direction (13) and connected via a single connecting element (45) both to each other and to the base housing (11).Type: GrantFiled: August 6, 2015Date of Patent: July 3, 2018Assignee: WABCO GmbHInventors: Stefan Knoke, Karsten Runge, Andreas Teichmann, Ingo Torhoff

Patent number: 9963135Abstract: The invention relates to a valve unit for modulating the pressure in a pneumatic brake system, comprising a brake pressure inlet, a brake pressure outlet, a vent outlet, a diaphragm inlet valve, a diaphragm outlet valve, and a pilot valve for each diaphragm valve, the pilot valves being arranged in an elongate valve housing (having a main housing and a housing cover. The inlet valve pilot valve and the outlet valve pilot valve are arranged substantially centrally above the diaphragms of the inlet valve and the outlet valve in the housing cover and with the actuation axes of the pilot valves running parallel to the parting plane, and the housing cover includes a central insert which has valve bores and control channels and into which the solenoids and the mechanical components of the pilot valves are inserted, the central insert being encapsulated with a plastic material.Type: GrantFiled: August 6, 2015Date of Patent: May 8, 2018Assignee: WABCO GmbHInventors: Dirk Füllgrabe, Stefan Knoke, Karsten Runge, Andreas Teichmann
