摘要:
The present invention relates to a fuel cell (1) with an air-supplied cathode region (2) and a device (3) for determining the oxygen content in the supplied air. It is characterized by the fact that a fuel cell operating state control unit (3) is provided, which determines the operating state for the mobile operation of the fuel cell based on the oxygen content that was determined.

For the detection of undissolved gas in the brake system; hydraulic pressure is built up and at least one characteristic value for the pressure buildup such as the master cylinder pressure, the brake pedal distance, the drop in storage chamber pressure, etc., is checked to see if it exceeds a predetermined limit value. If this limit value is exceeded, it is assumed that there is an unacceptable amount of undissolved gas in the hydraulic component of the brake system.

A surface cleaning head is provided comprising a dome-shaped, downwardly open housing, in which at least one spray arm is mounted for rotation about an axis of rotation, wherein the spray arm bears at a distance from the axis of rotation a nozzle which can be acted upon with cleaning fluid subject to pressure and revolves around the axis of rotation together with the spray arm, and comprising a protective disk which covers the at least one spray arm towards the open underside of the housing and defines a ring-shaped fluid passage for a stream of fluid to pass through, said fluid passage being penetrated by retaining bars, wherein the at least one spray arm is rotatable relative to the protective disk. The retaining bars are arranged so as to be distributed unevenly in circumferential direction.

The invention relates to a high-pressure spray gun for a high-pressure cleaning appliance, comprising a housing having arranged therein a valve with an inlet channel and an outlet channel and a closing body, which is adapted to rest in a sealing manner on a sealing surface arranged between the inlet channel and the outlet channel, and which interacts with a hand lever, an insert nipple being insertable into the inlet channel and fixable in an axially immovable manner for connection of a liquid supply line. To further develop the high-pressure spray gun in such a way that a liquid supply line can be connected to and separated from the valve in a simple way, it is proposed in accordance with the invention that the high-pressure spray gun comprise an immovable securing clip with two securing parts, which are insertable into diametrically opposed lateral openings of the inlet channel in order to engage behind the insert nipple, and which are spreadable apart in a spring-elastic manner by an actuating element which is displaceably arranged in the housing.
摘要:
A method and an apparatus for controlling a braking system, the control unit of which controls the wheel brakes receiving reference variables for control purposes. If these reference variables are not available, the control unit produces, on the basis of a predefined braking force distribution between the front and rear axles and in the context of an emergency mode, reference variables which it sets at the wheel brakes.
摘要:
A hydraulic motor vehicle brake system with dual brake circuits having an anti-skid system and is also further developed to improve vehicle tracking by ways of automatic braking, especially during cornering. During automatic braking, an auxiliary pressure source delivers a pressure medium to an anti-skid system to supply the wheel brakes. For this purpose a separating piston for each brake circuit is located between the auxiliary pressure source and the anti-skid system. For the purpose of keeping costs low, the two separating pistons are accommodated in an integral cylinder with a blind bore.
摘要:
A hydraulic motor vehicle brake system having anti-skid system and further developed to improve vehicle tracking, especially during cornering by means of automatic braking. With automatic braking an auxiliary pressure source delivers a pressure medium to an anti-skid system, by means of which braking pressures can be individually adjusted in the wheel brakes. For this purpose a cylinder with separating piston sections is located between the auxiliary pressure source and the anti-skid system, wherein the separating piston is installed into 2/2-way valves including lip sealing rings. The embodiment in accordance with the invention include cylinders, with valve openings in cooperation with the lip sealing rings, which results in economical 2/2-way valves.
