摘要： The invention relates to a drive system having at least one hydraulic actuator (2), which is supplied with pressure medium (4) by means of at least one pressure-medium pump (3) in a main circuit, the pressure-medium pump (3) being a rotational-speed-controlled pressure-medium pump that is driven by a motor (5) at a variable rotational speed and a controlled torque, said drive system being characterized in that leakage fluid (7) that escapes from a displacement chamber (6) of the pressure-medium pump (3) is discharged through a fluid-conducting connection (8) having at least one check valve (9, 16), and the at least one check valve (9, 16) is installed in the fluid-conducting connection (8) in such a way that the check valve prevents pressure medium from flowing back out of the main circuit into the displacement chamber (6) or another interior chamber of the pressure-medium pump (3) and feeds leakage fluid (7) into the main circuit of the drive system (1) when there is a slight excess pressure.

摘要： An electromagnet for actuating valves includes a sheath-like magnet housing encompassing a pole core forming a one-sided closure of the housing. The housing is connected to the pole core by an annular groove in its periphery, by an O-ring accommodated in the groove as a sealing element and by an annular groove in the magnet housing. The magnet housing forms bearing surfaces joined in positive fit to the inner walls of the annular groove and a sealing surface located on the O-ring.
