The invention relates to a piloted valve, particularly a piloted proportional throttle valve, having a valve piston (29) displaceably guided in the longitudinal direction in a valve housing (13) having a fluid inlet (2) and outlet (1), the front side (27) whereof can be pressurized against a main valve seat (25) by fluid pressure acting on the back side thereof, having a pilot valve device comprising an actuating member (7) displaceable in the longitudinal direction by means of an electrically actuatable magnet system (4), working together with a pilot valve seat (37) in a bore (17) of the valve piston (29) connecting the back side thereof to the fluid outlet (1) on the front side of the piston, in order to reduce the fluid pressure on the back side of the piston (29) for an opening motion when the pilot valve seat (33) is released, a flow baffle device (39) being disposed between the back side of the piston and the fluid inlet (2) of the housing (13) for building up the fluid pressure pressurizing the piston (29) against the closed position thereof by introducing pilot fluid, characterized in that the flow baffle device (39) comprises a device for performing filtration, preferably gap filtration, of the pilot fluid.

A crane with a boom, on which running tracks for cable carriers are disposed, having two running tracks for the cable carriers, which engage into one another with a positive lock. One running track is connected with the crane or the boom, and the other running track is displaceable on the crane or the boom.

The invention relates to a device for treating the human and / or animal body, for example a core drill, especially an intramedullary reamer for tubular bones, which has a drill head (12). Said drill head (12) is connected to a flexible shaft (14) which is in turn connected by a shank (16) to a drilling machine. The core drill also has a rinsing unit (18) by which means drilled material is removed in the area of the drill head (12). The rinsing unit (18) is connected to a rinsing channel (30) for this purpose, said rinsing channel being configured between the bore and the outside diameter of the flexible shaft (14). The drill head (12) has slits (34) which are connected to an inner cavity (36) of the drill head (12). Said cavity (36) is in turn connected to an inner channel (40) provided in the flexible shaft (14). The rinsing medium is guided into a rinsing head (42) through said inner channel. In the rinsing head (42), the rinsing medium enters a ring-shaped channel (58) through slits (60) provided in the flexible shaft (14). Said ring-shaped channel (58) is connected to a channel (54) to a which a suction device is connected by flexible tubing (56).

A rolling-element bearing for bearing rotating components in vacuum devices comprises a plurality of rolling elements (10) arranged between bearing elements (12, 14). A bearing compartment (26) is for example closed by sealing elements (22, 24) on both sides. Said sealing elements (22, 24) have a minor sealing gap (s). The rolling-elements bearing according to the invention are used in vacuum sections in which a pressure of less than 10-3 mbar prevails.

A counterholder (10) for supporting at least a first of two boundary surfaces (12a, 14a), between which a medium (15) is arranged, via which a first compressive force acting on the first boundary surface (12a) and a second compressive force (F2) acting on the second boundary surface (14a) and directed counter to the first compressive force (F1) are exerted, at least temporarily. The counterholder(10) has a shell of elastically deformable design (16) at least in one contact area for positioning at a boundary element (12), which provides the first boundary surface (12a) on a contact side opposite the first boundary surface, and within which, a non-Newtonian, shear-thickening fluid (18) is arranged.

The assembly to separate tobacco from a compressed tobacco cake has a housing frame (11) with a cutting unit (12) and a rotating cutting plate (13), fitted with a number of cutting blades and rotating around an axis (14). A grinder (21) sharpens the cutting plate with a common counter surface (15). The assembly has at least one sensor (26) near the grinder and / or the counter surface, which registers the sound of the cutting plate in contact with the counter surface as an acoustic body sensor working on the piezo principle, and is linked to the grinder.
