Abstract: A torsional vibration damper has a drive-side transmission element; a damping device having a plurality of energy accumulators; a driven-side transmission element configured to be rotationally deflected coaxial to the drive-side transmission element and which is connected to the drive-side transmission element via the damping device; and sliding elements arranged in one of the drive-side transmission element and driven-side transmission element so as to be movable in a circumferential direction. The sliding elements have: (i) circumferential projections for the energy accumulators, these circumferential projections being directed toward adjacent sliding elements, and/or (ii) penetration spaces for circumferential projections provided at the adjacent sliding element.

Abstract: A control device for pressurized fluids includes a valve mechanism actuated by a first device incorporating electromagnets in a first housing, and a second device incorporating a circuit board for controlling the valve mechanism in a second housing. Pins on the first device and sockets on the second device automatically form an electrical plug-type connection when the housings are joined. Each socket is received in a first portion of a through-hole provided in a mount supported on the circuit board such that it extends into a corresponding through-hole in the circuit board. A second portion of each through-hole in each mount has a funnel-shaped guide opening toward the pins. A pressure sensor supported by the circuit board forms a plug-type engagement with a port extending from the valve mechanism when the housings are joined. Contacts extend from the sensor into holes in the circuit board.

Abstract: A pre-engagement unit for a braking pressure modulator for a pressure regulating circuit includes a first pneumatic inlet, a second pneumatic inlet, a first pneumatic output terminal, and a second pneumatic output terminal. The unit includes an electrically actuated valve system having a plurality of solenoid valves and a plurality of electrical terminals connected to output terminals of an electronic control unit. An electric braking command signal transmitter delivers a driver initiated electric brake value setting to an input of the electronic control unit. Under normal conditions, a supply pressure and a redundancy pressure are delivered at the first pneumatic output terminal to be converted by an air quantity augmenting relay valve to a braking pressure. In case of failure of the electronic braking system, the redundancy pressure is delivered at the first pneumatic output terminal to be converted by the air quantity augmenting relay valve to the braking pressure.

Abstract: A pre-engagement unit for a braking pressure modulator for a pressure regulating circuit of an electronic braking system includes an electrically actuated valve system with three substantially identical 2/2-way solenoid valves. First and second terminals of the 2/2-way solenoid valves are selectively connected to the pneumatic inlets and output terminals of the pre-engagement unit, and to each other so that the first 2/2-way valve serves as an air admission valve for supply pressure, the second 2/2-way solenoid valve serves as an air admission/exhaust valve for redundancy pressure, and the third 2/2-way solenoid valve serves as an exhaust valve. Thereby, the pressure in the pressure regulating circuit can be increased, decreased, or maintained. Desirably, the first, second, and third 2/2-way solenoid valves are connected in parallel to each other.

Abstract: A valve system for the pre-engagement unit of a vehicle braking pressure modulator contains solenoid valves, which are controlled by an electronic braking system. Pneumatic pressure is fed into a brake cylinder on the vehicle wheels via a pressure regulating channel of the pre-engagement unit. The solenoid valves are configured as cartridge solenoid valves, so that assembly is simplified, and utilization of elastic tolerance compensating elements is unnecessary. A preferred embodiment includes three cylinder bodies connected end-to-end with no increase in cylinder diameter. This embodiment enables the use of identical armatures and identical magnet coils for different valve types, such as 3/2-way solenoid valves or 2/2-way solenoid valves. Also, these valves may be configured as normally open or normally closed, with identical outside dimensions. As such, three cartridge solenoid valves can be combined into a compact triple valve cartridge unit that further simplifies the assembly process.

Abstract: A rail element for the reception of article supports with a metallic profile strip (20) having a cross section with at least two legs (2, 3) defining a right angle (4), having openings (5) in one of the legs (2) for the reception of hook-formed brackets of article supports. The openings are provided in an aligned manner at a mutual distance in the main direction of extension of the rail element according to a modular dimension which allows a height-adjustable arrangement of the article supports. In the other leg (3) openings (6) are provided as well and arranged at the same height as the openings (5) in the first leg (2). Both facing openings (5, 6) are connected with a clearance (7, 8) forming a continuous recess which extends over the right angle (4).
