Patent number: 10302217Abstract: A valve unit includes a positioning device for converting a rotary motion into a linear motion, a valve rod, a drive unit, a drive shaft with an eccentric arranged thereon, a coupling element comprising a slot, and an output shaft arranged at the eccentric which moves in the slot of the coupling element. The valve rod is connected with the coupling element. The valve rod is linearly movable with the coupling element between an initial position where the valve is closed and an end position. The slot comprises a guide path which cooperates with the eccentric having an angle with a plane perpendicular to a direction of movement of the adjusting element. The initial position of the eccentric is a position which is located before a dead center existing for an axial movement of the output shaft. The dead center is passed during a rotational movement of the drive shaft.Type: GrantFiled: February 3, 2015Date of Patent: May 28, 2019Assignee: PIERBURG GMBHInventors: Andres Toennesmann, Martin Nowak, Andreas Koester

Patent number: 10151307Abstract: A magnet pump for an auxiliary unit of a vehicle includes an inlet, an outlet, an electromagnet comprising an armature, a core, a coil and a yoke, a cylinder comprising an outlet opening, and an axial piston which moves in the cylinder. The axial piston includes first and second axial piston parts, a gap arranged between the first and second axial piston parts, and an axial through bore. A first non-return valve is biased between the first and second axial piston parts and against the axial piston. A second non-return valve is biased against the outlet opening of the cylinder. The first axial piston part is connected with/is integrally formed with the armature and is lifted off the second axial piston part. A fluidic connection exists between the inlet and the outlet via the gap when the first axial piston part is lifted off the second axial piston part.Type: GrantFiled: August 12, 2014Date of Patent: December 11, 2018Assignee: PIERBURG GMBHInventors: Andres Toennesmann, Matthias Baden, Costantino Brunetti, Michael Sanders, Andreas Koester

Patent number: 9016266Abstract: A valve device for an internal combustion engine includes a multi-part housing. A drive unit generates a rotational moment. The drive unit is arranged in a motor chamber. A transmission unit is arranged in a transmission chamber. An eccentric is configured to be driven by the transmission unit. A valve rod is configured to be displaceable in translation. The valve rod extends into a valve rod displacement chamber. A coupling element converts a displacement of the eccentric into a translational displacement of the valve rod. A valve seat is arranged between an inlet and an outlet. A valve closing body is attached to the valve rod. The valve closing body is configured to be lowered onto the valve seat and lifted off the valve seat. A cover is disposed between the eccentric and the coupling element. The cover is configured to separate the transmission chamber from the valve rod displacement chamber.Type: GrantFiled: November 23, 2010Date of Patent: April 28, 2015Assignee: Pierburg GmbHInventors: Martin Nowak, Andreas Koester, Andres Toennesmann, Heinrich Dismon

Publication number: 20140230582Abstract: An actuating apparatus includes a housing, an actuating unit, a receiver element, and a transmitter element. The actuating unit comprises a first end with a circular arc-shaped contour whose circular arc central axis is configured to act as a first pivot axis. The actuating unit is configured to be moved via an actuator and to undertake a translational main movement and a pivoting movement. The translational main movement is superimposed by the pivoting movement. The receiver element is fixedly arranged in the housing. The transmitter element comprises a magnetic field. The transmitter element is configured to be translationally movable, to be biased so as to bear against the first end of the actuating unit, and to cooperate with the receiver element.Type: ApplicationFiled: July 17, 2012Publication date: August 21, 2014Applicant: PIERBURG GMBHInventors: Andres Toennesmann, Andreas Koester, Martin Nowak, Michael Schaefer, Michael Breuer

Publication number: 20130132003Abstract: A method for determining a resulting total mass flow to an exhaust gas mass flow sensor involves providing an exhaust gas mass flow sensor comprising a first sensor element and a second sensor element. The second sensor element comprises a first temperature sensor and a second temperature sensor arranged in a row in an exhaust flow direction. A specific heat output is determined at the exhaust gas mass flow sensor with the first sensor element and the second sensor element. A value of a summed mass flow is determined from a stored first characteristic map, a specific heat output being a function of the value. A normalized temperature gradient is determined. A back flow portion is determined from a stored second characteristic map, the back flow portion being a function of the specific heat output in dependence on the normalized temperature gradient. The resulting total mass flow is determined.Type: ApplicationFiled: July 5, 2011Publication date: May 23, 2013Inventors: Andres Toennesmann, Karsten Grimm, Sven Nigrin
