    Abstract: The regulating device is used in connection with a vehicle-mounted appliance for scattering bulk materials, such as salt or gravel, on a road, where the rate of distribution depends on vehicle speed, the volume being changeable. The vehicle engine drives an adjustable pump, supplying pressure medium to hydro motors driving a scatter tray and dosing appliance respectively. The flow of pressure medium is divided, in a regulating valve into a constant flow and a residual flow. The former flows, via a pressure scale and adjustable throttle combining to form a control device, to a hydro motor for scatter tray drive. This together with a pressure medium flow delivered by a second pump dependent on vehicle speed, serves to drive the dosing appliance and influences the supply volume of the adjustable pump.

    Abstract: The invention relates to a device for a hydraulic unit, in particular in anti-skid systems for vehicle brake systems, which has a radial piston pump. The eccentric driven by a drive shaft in the pump meets pump pistons also located in the pump, usually in the region of high stroke variation speed. An resultant mechanical and hydraulic vibration, which causes noise and annoying movement at the brake pedal, is counteracted according to the invention in that a resilient intermediate element is disposed between the pump pistons and the eccentric element, and the eccentric is driven via a torsionally elastic coupling.

    Abstract: A master brake cylinder including a re-aspiration valve which is disposed as a central valve in pistons of the master brake cylinder. The re-aspiration valve has a porous body, comprising porous metal, which forms a flat valve seat at one end. The sealing body of the re-aspiration valve is raised gently from the valve seat even at high ambient pressure, which makes a re-aspiration valve embodied in this way particularly suitable for use in master brake cylinders of brake systems having slip control. Because the porous body comprises porous metal which differs in length from its wall surface at one end to its axis to form a conical void space. The porous body has an axial flow resistance that decreases from the outside wall inward to its axis.

    Abstract: A control valve for maintaining the temperature respectively the viscosity of pressure fluid passing therethrough substantially constant comprises a control slide provided with a throttle bore and downstream of the control slide a precontrol valve in which an end portion of an element expandable by the temperature of the pressure fluid is arranged. When pressure fluid with a certain pressure is fed through the inlet end of the control valve, the control slide is lifted from its seat and the precontrol valve opens. All of the pressure fluid entering the control valve is passed through various bores and annular gaps along the precontrol valve to the temperature expandable element. When the fluid reaches the desired maximum temperature a bypass for the fluid is created by the expandable element and a control pin actuated by the latter. thereby the throttle action of the control valve is reduced and overheating of the pressure fluid avoided. A throttle gap between the control slide and the housing will assure removal of any air contained in the pressure fluid and a further throttle gap formed between an end face of the control slide and a disc attached thereto serves to catch any foreign particles in the pressure fluid which will be flushed away after moving of the control slide away from its seat.
