Abstract: A trailer ABS system is provided with an ABS valve in which pressure to the control chamber is switchable by a 2/2 solenoid valve, the solenoid valve being switchable between a first position in which the control chamber is pressurized by the control pressure and a second position, in which the control chamber is connected to the exhaust. The braking ECU is operable to actuate the solenoid between the first and second positions to thereby provide ABS functionality.

Abstract: A valve arrangement for a trailer brake module in a monoblock housing includes an input for a brake supply pressure, an input for a brake control pressure, and an output for supplying a brake pressure to braking devices on a trailer. The valve arrangement includes a relay valve, and includes control solenoids which are arranged substantially transversely to the direction of motion of the relay valve piston.

Abstract: A valve arrangement for use in a parking brake system of a commercial vehicle or trailer, includes a differential piston having a first section and a second section, wherein the second section has a smaller diameter compared to the first section, and wherein there is a fluidic connection between the first section and the second section. The arrangement includes a housing with a bore, in which the differential piston is adapted to move. The bore has at least two sections, wherein the first section corresponds to the diameter of the first section of the differential piston, and the second section corresponds to the diameter of the second section of the differential piston, and wherein a step is formed between the first section and second section of the bore. A first passage and a second passage are arranged and axially spaced in the bore, and a third passage is arranged in or next to the second section of the bore.

Abstract: A parking valve for manually actuating a spring-loaded parking brake, includes: a housing with a port that can be fluidically connected to a release chamber of a spring-loaded brake cylinder, a port that can be fluidically connected to a brake supply reservoir, and a ventilation port; a slide for manual actuation and which can be moved along a full section between two end positions inside the housing. The slide assumes positions along the full section, in which, as a result of at least one seal, there is no fluidic connection between the port to the release chamber and the ventilation port, and assumes other positions along the full section, in which, as a result of the at least one seal, there is no fluidic connection between the port of the release chamber and the port to the brake supply reservoir.

Abstract: A utility vehicle control device for a parking brake device of a trailer vehicle includes a pneumatic supply connection, a control connection for controlling a spring brake cylinder, a directly manually actuatable parking valve, a first connection line and a control valve for controlling the parking valve. The parking valve is arranged in the first connection line, and wherein as a result of the parking valve, the supply connection and the control connection can be connected via the first connection line. A control line branches from the first connection line. The control line is connected to a first pneumatic control input of the control valve, wherein the control valve has a second pneumatic control input.

Abstract: A valve housing, in particular for a level control valve and/or a rapid-action valve, is provided. The valve housing has a first housing part and a second housing part. The first housing part and the second housing part can be brought together in an assembly orientation in relation to one another in order to establish mechanical contact between the first housing part and the second housing part and can be moved out of the assembly orientation into a securing orientation in relation to one another. The first housing part and the second housing part are designed to be secured or securable to each other mechanically in the securing orientation.

Abstract: A valve, in particular a pneumatic suspension valve for a vehicle, is provided. The valve includes a valve body with a driver. The driver has a receiving section for receiving an actuating lever which can be fixed on the driver. Said receiving section is design to receive, without retrofitting the receiving section, an actuating lever having a first cross-sectional profile to receive an actuating lever having a second cross-sectional profile which is different from the first cross-sectional profile.

Abstract: The invention relates to a process for the preparation of 3-{2-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]ethyl}-6,7,8,9-tetrahydro-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one of the Formula (I), and pharmaceutically acceptable acid addition salts thereof by subjecting the oxime of the Formula (II), to ring-closure in the presence of an alkali hydroxide, alkali carbonate or alkali-C1-4 alkoxide in an inert organic solvent, converting the base of the Formula I thus obtained into an acid addition salt or setting free the base of the Formula I from an acid addition salt thereof which comprises reacting a halogen derivative of the general Formula (XIV), (wherein Hal is halogen) with piperidine oxime derivative of the Formula (V), or an acid addition salt thereof in the presence of a base, and using by the ring-closure of the oxime of the Formula II formed a C1-4-alkanol as inert solvent.
