20090200502 | ELECTROMAGNETIC ACTUATOR FOR A HYDRAULIC DIRECTIONAL CONTROL VALVE - An electromagnetic actuator for a hydraulic directional control valve is provided. The electromagnetic actuator is used for adjusting a hydraulic directional control valve, for example, for the variable adjustment of the control times of an internal combustion engine. The electromagnetic actuator includes a housing ( | 08-13-2009 |
20100163128 | HYDRAULIC DIRECTIONAL VALVE - A hydraulic directional valve having an electromagnetic actuating unit and a valve section, an essentially cylindrical, blind hole-like receptacle being formed on one component of the actuating unit, a flange section of a valve housing of the valve section engaging in the receptacle, the flange section being provided with an angular groove which extends in a circumferential direction, and an essentially hollow cylindrical wall of the receptacle in the region of the annular groove engaging in said annular groove in such a way that it bears on the groove base of the annular groove, along the entire circumference of said annular groove. The torsional rigidity between the flange section and the wall is increased. In this context, particular emphasis is placed on processing reliability and economic viability of the connecting process. | 07-01-2010 |
20110084018 | RING FILTER - A ring filter with a frame and a filter fabric. The frame has two axially spaced apart ring-shaped frame elements which are connected to one another by transverse struts. Between the frame elements and the transverse struts the filter fabric is arranged, and frame has two open ends which are located opposite each other in the circumferential direction. | 04-14-2011 |
20110121218 | ELECTROMAGNETIC ACTUATING UNIT OF A HYDRAULIC DIRECTIONAL VALVE - An electromagnetic actuating unit of a hydraulic directional valve, which has an armature and a first and a second magnet yoke. The first and the second magnet yokes at least partially bind an armature space, the armature is arranged in the armature space so as to be axially displaceable, and the first and the second magnet yokes face each other in the axial direction of the armature. | 05-26-2011 |
