Abstract: A manipulating device includes a gripper (11) for gripping workpieces (19) by way of a negative pressure. A suction pump for generating and feeding the negative pressure as well as at least one valve (24) are disposed in a casing (14). The casing is connected with the suction gripper (11). The negative pressure can be applied to the suction gripper (11) by means of the valve (24).

Abstract: A valve battery, including a plurality of base plates, each having a generally polygonal outer contour, a window-shaped recess therein, and two side faces, a face of one plate corresponding a face of an adjacent plate and sealingly engaging one another, closure plates being provided on the free end surfaces, a plurality of electrically actuatable individual valves mounted in the base plates, each having an inlet port, an outlet port, and an electrical connection, the mounted valves not protruding from the faces of the base plates, at least one of the base plates (4) having an associated vacuum device (31) and a compressed air connection (32) on one of the end surfaces for creating a vacuum, being interconnected for control by another of the said base plates (1) having one or more associated valves which are continuous valves (14), an inlet connection associated with each of the base plates, provided on one of the elongated side surfaces thereof, an outlet connection (A1,A2) associated with each of the valves,

Abstract: A linear unit (10) is provided with a cylinder (50) and a pressure-fluid actuated piston (52). The piston (52) runs in a borehole (51) of the cylinder (50). A slider (55) runs at the cylinder (50). A band (53) connects the piston (52) to the slider (55) and leads via deflection structure (54a, 54b) at the heads (11a, 11b) of the cylinder (50). Valves (15a, 15b) are screwed into the cylinder heads (11a, 11b) for feeding a pressure fluid to and discharging a pressure fluid from the borehole on two sides of the piston (52). The linear unit (10) provides an increased liberty of direction in a position-mounting of the linear cylinder heads (11a, 11b) and of the linear unit with valves (15a, 15b) as well as in the positioning of the connection terminal pieces. The linear unit (10) is flexible and is of modular construction and allows different types of device components to be flanged in the same position.

Abstract: An actuating magnet comprises a magnet body (10), an exciting winding (15) rranged in the said magnet body (10) and a radially movable armature (17) having a pre-determined first radial cross-sectional surface. One end of the armature (17) having a second radial cross-sectional surface (19) substantially larger than the said first cross-sectional surface (20) forms a pole piece (18). Between the said pole piece (18) and a wall (11) of the said magnet body (10) which covers in the radial direction at least part of one end face of the said exciting winding (15) there is provided an air gap (20).In order to increase the actuating force of the magnet without changing its outer dimensions and to provide a closed system, the wall (11) covers the said end face of the exciting winding (15) and shields it magnetically, the pole piece (18) is arranged opposite to the inside of the said wall (11) and the air gap (20) extends in the radial direction (FIGS. 1a+b).
