Abstract:
A mounting element for receiving a sensor has a sensor receptacle having an essentially cylindrical or funnel-shaped geometry. The sensor receptacle has openings for wetting of the sensor by a medium. The sensor is fixed in the sensor receptacle without gaps or play by a filling compound, which is in turn mounted by a mechanical undercut.
Abstract:
An electrohydraulic unit for controlling pressure in slip-controlled motor vehicle brake systems comprises a hydraulic block, with an electric motor mounted on a first side, and a control unit secured to an opposite second side of the hydraulic block. Electrical terminals of the electric motor are passed through the hydraulic block and are embodied inside the control unit as resilient contact means. The contact means engage contact faces of the control unit with an initial stress. The resilient contact means make electrical plugs in the control unit unnecessary, and they compensate for tolerances in and transverse to the mounting direction of the electric motor and control unit.
Abstract:
This invention relates to a piston pump in a brake system having a piston, which is drivable in a reciprocating motion in a cylinder by an eccentric tang. To avert damage to a ring seal, a support ring is provided which keeps the ring seal spaced apart from a guide sheath for the piston in the cylinder by a distance that is at least as long as a stroke length of the piston. This prevents running scratches on the piston from coming into contact with the ring seal.
Abstract:
A hydraulic dual-circuit brake system with an anti-skid system and traction control in motor vehicles which has a four-channel hydraulic unit with electromagnetic control valves and a return pump having two separate pump elements. For supplying brake pressure during traction control, an additional hydraulic unit is provided, which has a charging valve for connecting the brake fluid tank to a pump element, which pump element is assigned to a brake circuit containing at least one driven wheel, and a reversing valve for alternatingly connecting this pump element to the master brake cylinder or the brake fluid tank. To provide economical brake pressure supply during traction control, the aforementioned pump element is embodied as a self-aspirating high-pressure pump, and a check valve having a flow direction toward the pump element is incorporated into the connection between the control valves disposed in the brake circuit assigned to this pump element and the inlet of the pump element.

Abstract:
A housing for an electronic circuit is provided with a single-part seal for sealing a clearance space between a floor plate and a cover, through which exposed electrical conductors are led, which connect the circuit on the inside of the housing to the surroundings. The floor plate, the cover and the conductors are made of the same kind of material, e.g., a metal. The floor plate and the cover are made of aluminum and the conductors of copper.
Abstract:
A device for drying and/or wetting a mop with a removable container for receiving a liquid. The device has a receiver for the container with a collecting base which is located underneath the container when the container is disposed in the receiver, and the device has liquid conveying devices for removing or feeding the liquid. The collecting base extends underneath the liquid conveying devices. The liquid conveying devices have a motor for driving a pump for wetting the mop with liquid from the container and for driving a drying device for removing liquid from the mop. The drying device and the motor are fixedly connected to the device and the pump is arranged in the container. The pump is operatively connected to the motor via a separable coupling in a driving manner.

Abstract:
A known vehicle brake system having four wheel brakes, belonging to two brake circuits, for four wheels has an anti-skid apparatus with two electrically controllable brake pressure modulators, two wheel rotation sensors, and two brake pressure adaptors. The wheel rotation sensors are assigned to one front wheel and one diagonally opposed rear wheel, and each controls one brake pressure modulator, which belongs to the same wheel as the wheel rotation sensor. The brake pressure of a wheel brake located on the same axle on the opposite side of the vehicle is also controlled by a brake pressure modulator via a brake pressure adaptor. If only one wheel rotation sensor is provided per axle, only the wheel associated directly with the wheel rotation sensor can be braked optimally. The other wheel on the same axle may be overbraked or underbraked. This interferes with controllability of the vehicle and/or may have the disadvantage of overly long stopping distances. In the novel vehicle brake system, each of the two wheel rotation sensors is assigned to a separate front wheel and controls one brake pressure modulator for its respective front wheel. The two rear wheel brakes are each coupled via a brake pressure adaptor to the brake pressure modulator on the same side. A pressure reduction for the right front wheel that is effected in anti-skid operation results in a pressure reduction in the same direction for the right rear wheel.
