Publication number: 20220278518Abstract: Busbar comprising a supporting body (1) made of a tough-hard material, and at least one electrical conductor (2.1, 2.2, 2.3, . . . ), wherein the conductor (2.1, 2.2, 2.3, . . . ) is connected to the supporting body (1). The supporting body (1) comprises a seal (3) that is made of a rubber-elastic material, which encloses the conductor (2.1, 2.2, 2.3, . . . ) on the outer circumferential side with an annular sealing region (4) in a sealing manner.Type: ApplicationFiled: February 24, 2022Publication date: September 1, 2022Inventors: Rouven Ratfisch, Ralf Heldmann, Guenter Ziegler, Markus Clemens, Juergen Mall

Patent number: 9388921Abstract: A plug-in piece 1 for sealing connection of two mutually assigned cylindrical surfaces includes an essentially tubular support body 2, which on its ends exhibits annularly encircling sealing elements, which can be made to engage to produce a sealing connection with the cylindrical surfaces to be sealed, wherein at least one of the sealing elements is configured as an annularly encircling sealing bead 3, 30 on the outer surface of the support body 2, with a spherically curved sealing surface. Provision is made that the spherical radius of the sealing surface (3, 30) is chosen so that the center of the sphere is roughly at the axis of support body (2) symmetry. Thus, the compression forces are ensured to remain largely constant, independent of the angular setting over the entire surface of the sealing bead.Type: GrantFiled: August 28, 2013Date of Patent: July 12, 2016Assignee: Carl Freudenberg KGInventors: Hans Unger, Ralf Heldmann, Ingo Stephan, Markus Clemens, Carsten Hartmann, Ernst Jakob, Stephan Reddig

Publication number: 20150152754Abstract: A seal including a sealing ring (1) made from an elastomeric material, an intermediate ring (2) made from a polymeric material, and a supporting ring (3), the sealing ring (1), the intermediate ring (2) and the supporting ring (3) being arranged concentrically with respect to one another, and the sealing ring (1) and the supporting ring (3) being arranged in each case on the sides of the intermediate ring (2) which face away axially from one another. The sealing ring (1), the intermediate ring (2), and the supporting ring (3) form a pre-assembled unit (4).Type: ApplicationFiled: June 3, 2014Publication date: June 4, 2015Applicant: CARL FREUDENBERG KGInventors: Ralf HELDMANN, Markus CLEMENS, Ernst JAKOB, Günter ZIEGLER

Publication number: 20140197599Abstract: A sealing arrangement includes a double seal for sealing two chambers which are to be sealed off from one another and are each filled with a medium to be sealed. The double seal includes a first sealing ring disposed on a first side of the double seal and a second sealing ring disposed on a second side of the double seal. Each of the sealing rings has at least one dynamically stressed sealing lip contacting a surface to be sealed of a first machine element in a sealing manner. The sealing lips are arranged such that there is an axial distance between the sealing lips of the first and second sealing rings that are axially closest to one another. The first machine element is movable backwards and forwards in a translatory manner with a stroke. The axial distance is greater than the stroke.Type: ApplicationFiled: January 14, 2014Publication date: July 17, 2014Inventors: Olaf Nahrwold, Thomas Jaeck, Markus Clemens, Ernst Jakob

Publication number: 20120107650Abstract: A valve apparatus (4) is provided for a housing (2) of an electrochemical current source (1). Furthermore, the magnetic valve apparatus (4) is provided for, among other things, battery housings, fuel cell housings as well as chemical or biological reactors. As a result of using a magnetic valve apparatus (4) as an excess pressure valve, the housing (2) can be designed to operate safely even after years of use, and in addition, the valve apparatus (4) can automatically change back into the closed position after an opening and a pressure degradation and can thus build up again a protection against the penetration of fluids into the inner space (5) of the housing without external action.Type: ApplicationFiled: February 9, 2011Publication date: May 3, 2012Applicant: CARL FREUDENBERG KGInventors: Peter Kritzer, Olaf Nahrwold, Markus Clemens, Hans Unger, Thomas Kramer, Ingo Stephan, Georg Feurer

Publication number: 20120040217Abstract: A closing element for closing an opening (3) of a battery housing (1), including a cover (5), whereby the cover (5) comprises a connection groove (6) into which groove a wall (13) of a battery housing (1) can be inserted, whereby a connection piece (7) that can be deformed without destruction projects from the cover (5) and whereby the connection piece (7) is provided with a nipple (8). The closing element solves the problem of designing and further developing a battery housing in such a manner that it has a reliable tightness in normal operation but in abnormal occurrences it allows gases to escape without problems and in a directed manner without parts of the battery housing or of a valve being slung away in an uncontrolled manner.Type: ApplicationFiled: February 9, 2011Publication date: February 16, 2012Applicant: CARL FREUDENBERG KGInventors: Peter Kritzer, Olaf Nahrwold, Markus Clemens, Hans Unger, Thomas Kramer, Ingo Stephan

Patent number: 7017913Abstract: An axial shaft seal disposed between a housing wall and a rotating shaft includes an outer ring insertable into the housing wall in a stationary and sealing manner and an inner ring connectable to the shaft in a non-twisting and sealing manner. The outer ring includes a sleeve having a polymer material extending radially inward and having a spring bellows form. A radially inward end portion of the sleeve has a first sealing surface. The inner ring includes a ring flange extending radially outward so as to provide a second sealing surface for axially mating the first sealing face.Type: GrantFiled: June 25, 2003Date of Patent: March 28, 2006Assignee: Carl Freudenberg KGInventors: Thomas Klenk, Eberhard Bock, Thomas Kramer, Werner Hufnagel, Martin Heldmann, Markus Clemens, Gilbert Pataille
