Abstract: A mirror assembly (1) includes a mirror head (4), a bracket (5) fastened to the mirror head, and fastening elements (6) located at the bracket at a distance from the mirror head and connectable to the wing mirror (2) of a vehicle (3). The bracket has bracket parts (7, 8) joined in a longitudinal direction and mutually connected through a pivoting element (9), wherein a bracket part (7) faces towards the mirror head (4) relatively to the pivoting element and another bracket part (8) faces away from the mirror head (4) relatively to the pivoting element. Because one of the fastening elements is located at the bracket part (7) facing the mirror head and another of the fastening elements is located at the bracket part (8) facing away from the mirror head, the mutual orientation of the fastening elements can be adjusted to the exterior shape of the wing mirror.

Abstract: Auxiliary drive for a trailer such as a caravan. Said drive consists of a drive unit with a gearwheel. Through linear movement of the drive unit relative to the chassis, said gearwheel can be brought into engagement with a ring gear fitted either on the brake drum of a wheel of the vehicle or on an auxiliary part such as a covering drum fitted over said brake drum. The ring gear preferably lies in a plane outside the plane bounded by the inside of the wheel.

Abstract: A utilities connecting unit for connecting motor vans and house trailers with networks or sources of electricity, gas, water, antenna voltage and the like, is inserted into an opening in the floor of the motor van or house trailer. The connecting unit includes a rotatable and/or pivotable arm with integrated utility leads and pipelines, which can be moved between a retracted position and an extended position in such a manner, that, in the extended position, it protrudes laterally from the outline of the motor van or house trailer.

Abstract: A brake operating mechanism engages on an overrun brake present on a trailer, such as a caravan. The brake mechanism includes an actuator operated by pressurized air supplied by a buffer store via a valve controlled by a control unit. Downstream of the brake valve is a valve which is open in the non-operative state and closed during operation. A throttle opening is also provided, the drain capacity of which is greater than the pump capacity of an air pump located upstream of the brake valve and connected to the buffer store. As a result, the actuator moves back under all circumstances, i.e., braking action does not take place, and overheating is effectively prevented.

Abstract: The present invention relates to a valve device for flow control in a distributor of a liquid-operated heat or cold energy supply system with a flow measuring unit to measure a flow rate of the liquid and with a control element to adjust a flow area for the liquid, the maximum flow area being variable by rotation of the control element, the control element being designed as a first disc with at least one flow limiting aperture and being part of a control unit, and the control unit comprising a second disc which exhibits at least one flow aperture, is arranged in parallel to the first disc and adjoins said first disc, forming a tight connection, the at least one flow limiting aperture and the at least one flow aperture being positioned such that a total area made up of the areas of the at least one flow aperture and the at least one flow limiting aperture, which overlap each other, is variable as a function of a rotation of the first disc relative to the second disc around a rotational axis.

Abstract: One or a plurality of valve-operated branch pieces can be attached to any point of any pipe. To this end, two opposite openings (16, 18) are made in the pipe (10), and a branch valve body is clamped about the pipe in bracket-like manner at the prepared site.
