Abstract: An apparatus for weighing hard gelatine capsules or the like has a feed conduit and a discharge conduit, as well as a weighing receptacle that is disposed between them with virtually no cap. By means of a pawl, whichever of the lowermost hard gelatine capsule or the like is released in the feed conduit and pushed over onto the weighing receptacle by a lever can be pivoted into the feed conduit. A vane wheel is also present, whose vanes engages the feed conduit, the weighing receptacle and the discharge conduit and thereby form virtually closed-off transport chambers, each for one hard gelatine capsule or the like.

Abstract: An electric motor for moving or adjusting parts of vehicles such as windshield wipers and sunroofs have switching devices for shutting of the electric motor in at least one predetermined position of the movable part, for example also for shutting off the electric motors when the parts are disposed in their end positions. For this purpose, the switching devices have at least one permanent magnet that is for the actuation of switching contacts and, for example, is disposed on a switching gear, and have at least one sensor that is sensitive to magnetic fields. Different switching gears are stored for different sizes of parts to be moved. The invention sets forth a switching gear as an annular disk made of a magnetizable material, wherein the material is preferably comprised of a permanent magnet powder and a thermoplastic bonding. Such an annular disk is magnetized either in the immediate vicinity of an associated drive device or when installed in this drive device.

Abstract: A valve for controlling fluids, which is provided with a fluid-filled coupling chamber that is disposed between an actuator piston of a piezoelectric actuator and a piston that actuates a valve member. In order to compensate for a leakage in the coupling chamber that is intermittently under high pressure during a switching procedure, a filling valve is provided that is disposed radially on the coupling chamber, but outside the chamber, and this valve monitors an inflow from an inlet conduit that is under ambient pressure in the valve. In this manner, on the one hand, the clearance volume produced by the attachment of the filling valve is very small and on the other hand, the filling valve is independent of the accelerated movements of the pistons, i.e., independent of their acceleration forces. The valve is designated for use in fuel injection devices for internal combustion engines of motor vehicles.

Abstract: The valve has a seat valve with a hollow-conical valve seat and a closing member in the form of a spherical layer on a longitudinally drilled tappet. An inflow bore communicating with a pressure medium inlet discharges centrally into the valve seat. The largely pressure-equalized tappet is engaged by a magnet armature acting on the seat valve in a closing manner and by a restoring spring acting in the opening direction. The valve embodied in principle as a switching valve is controllable into stable intermediate positions on the basis of the following provisions: the cone angle of the valve seat is at most 90.degree.; the force at the closing member, originating in the restoring spring, is adapted such that it has a course that decreases monotonously with an increasing valve opening stroke (h); the magnet circuit of the valve is embodied such that the magnetic force (F.sub.

Abstract: A fuel injection pump for internal combustion engines, is proposed, with a distributor pump piston (6), which is supported in a housing bore (5) and on its jacket face, has a distributor groove (12), a filling groove (18), which is connected to a pressure relief chamber, and a pressure compensation surface (36). This filling groove constitutes a first leakage route (39) in the direction of the distributor groove (12) and constitutes a second leakage route (42) in the direction of an annular groove (20) in such a way that the pressure compensation surface, which is otherwise always closed by the inner wall of the bore (5), produces a high-pressure fuel supply by way of the first leakage route (39) in the direction of the pressure compensation surface (36) and this pressure compensation surface (36) is in turn relieved by way of the second leakage route (42) in the direction of the annular groove (20).

The valve has a valve seat which is embodied on a valve seat body which has at least one opening that can be closed by the valve member. A cross section of the at least one opening is embodied as essentially smaller than an entry cross section of the Laval nozzle that is disposed spaced apart from the valve seat.

Abstract: The invention relates to a hydraulic vehicle brake system with a hydraulic pump and a high pressure hydraulic accumulator for external power braking and a conventional master cylinder that is used as a braking power set point adjuster for external power braking and is used to actuate the brake system by muscle power in the event of a failure of the external power brake system. The system connects an intake side of the hydraulic pump to a low pressure hydraulic accumulator into which brake fluid travels from the wheel brake cylinders when the wheel brake pressure decreases. The system has the advantage that no connections of the hydraulic pump to a reservoir of the master cylinder are necessary, which in the event of a leak, would jeopardize the function of both the external power service brake system and the muscle power auxiliary brake system.
