IPC: F03C2/30
Filed: 1984-07-03
Abstract: In hydraulic motors and pumps, the shaft of the motor is set in rotation by pressure fluid being injected into chambers which are formed in a circular part. In the region of the chambers, the pressure fluid exerts pressure on the shaft with the interposition of control elements on which a pressure force acts outwards. A drawback of these conventional motors and pumps is the friction between the control element and the circular part, and the seal between the control element and the cavity. According to the teaching of the invention, the control elements are essentially cylindrical elements and, in addition, the walls of the cavities near the surface of the shaft are designed in such a way that an obtuse angle is formed with the surface of the shaft.

Abstract: A hydraulic brake system for automotive vehicles comprises a master cylinder (4) with at least two working chambers (3,5) and comprising at least two brake circuits. A first brake circuit is in constant hydraulic communication with a first working chamber (3) of the master cylinder (4), while a second brake circuit is connected to the second working chamber (5) of the master cylinder (4). A pressure control valve (1) is inserted into the connection between the working chamber (5) and the second brake circuit, the valve enabling to take influence on the pressure in the second brake circuit in a predeterminable fashion. The pressure control valve (1) is switchable by a slip monitoring electronics (62) so that braking pressure control in the second brake circuit will take place exclusively in the event of failure of the brake slip control apparatus. Thereby, the pressure variation in the wheel brakes, which is performed in a known fashion by suitable change-over of solenoid valves, will not be influenced negatively by the pressure control unit (1) when the brake slip control apparatus is intact.

Date Dec. 10, 1992It is possible to filter a suspension or emulsion in a filter bed of particulate filter medium by allowing the suspension to flow upwards through the filter bed simultaneously as the medium flows downwards through a filtering tank wherein filtration takes place. Filtration thus takes place during counterflow between suspension and filter medium. The supply of suspension takes place in the lower part of the filter bed and the filtered liquid phase is taken away from a zone above the filter bed. The polluted filter medium close to the bottom of the filter tank is taken out for conveyance to a washing apparatus above the filter bed and after washing is returned to the upper side of the filter bed. For providing a filter which has a considerably lower construction height for a given and unchanged volume of the filter medium, the washing apparatus is lowered so that its lower part is at a level below the upper surface of the filter bed.
