According to the invention, the pole core section has a stepped depression into which the armature can plunge and which, starting from the transition section, is subdivided into an annular collar, a shoulder, and a notch which is set back axially and radially. An axial dimension of the collar exceeds an axial dimension of the flange.Type: GrantFiled: July 20, 2009Date of Patent: June 24, 2014Assignee: Robert Bosch GmbHInventors: Juergen Gruen, Horst Bartel, Roland Schempp, Klemens Strauss

Patent number: 8757585Abstract: An actuating device, particularly for actuating valves that can be connected externally, includes a housing (10) and a coiled body (12) in the housing and having a coil winding (14). The winding encloses a pole tube (16) at least partially, having a pole core (20) connected at its free end. An armature (22) is guided in a longitudinally displaceable manner at least in the pole tube (16) within an armature chamber (24) and interacts with an actuating device (26) for actuating a valve part. The actuating part (26) is guided within the pole core (20) along an annular body (92), sealing the inside of the pole core (20) and the pole tube (16) relative to the surrounding area.Type: GrantFiled: June 5, 2009Date of Patent: June 24, 2014Assignee: Hydac Electronic GmbHInventors: Martin Bill, Florian Lauer

Publication number: 20140166915Abstract: A movable core sliding in a guide portion includes a small outer-diameter part, a large outer-diameter part, and a protrusion part. When a magnetic circuit is generated by energizing a coil, a magnetic attractive force inclining with respect to a center axis of the guide portion is generated between the guide portion and the movable core, and moves the movable core towards a stator core. Then, a sliding portion, which is provided over the whole periphery of the small outer-diameter part, and the protrusion part of the movable core are abutted on an inner peripheral surface of the guide portion, a clearance is generated between an outer peripheral surface of parts of the movable core except the protrusion part and the inner peripheral surface of the guide portion. Since the valve member can be opened by a small magnetic attractive force, a coil assembly can be made small.Type: ApplicationFiled: November 26, 2013Publication date: June 19, 2014Applicant: DENSO CORPORATIONInventors: Ryo ISHIBASHI, Akira TAKAGI

Publication number: 20140166916Abstract: An electromagnetic pressure-regulating valve includes a housing comprising a first, a second and a third port, a valve seat, a valve closure member, an electromagnetic drive, and a biasing device. The electromagnetic drive comprises a coil wound on a coil carrier, an armature, a core, and an electromagnetic return-path device. The armature moves between a first and second end position and acts on the valve closure member. The biasing device is configured so that, when a current does not flow, the armature, and thereby the valve closure member, is positioned in a fail-safe setting on the valve seat so that a connection from the third port to each of the first and second ports is closed. The valve seat is connected via a fluid channel to the first and second ports. The armature is steplessly adjustable between the first and second end positions in every setting.Type: ApplicationFiled: July 2, 2012Publication date: June 19, 2014Applicant: PIERBURG GMBHInventors: Werner Buse, Alvito Fernandes, Max Hermann, Roman Morawietz

Publication number: 20140158205Abstract: A method and apparatus for controlling a solenoid actuated inlet valve to a pump chamber of a piston pump. A control circuit energizes the solenoid to open the inlet valve in synchronism with the reciprocation of the piston and thereafter de-energize the solenoid to initiate closure of the inlet valve. The inlet valve is decelerated following de-energization of the solenoid thus effectively reducing engine noise attributable to the inlet valve.Type: ApplicationFiled: December 11, 2012Publication date: June 12, 2014Inventors: Yosuke Tanabe, Donald J.
