Publication number: 20150361836Abstract: A tappet (1) having a tube-like housing (2), which in the region of one of the end faces (3) thereof receives a roller (5) running on a pin (4) and serving for contact with a periodic stroke generator. The pin (4) is mounted via the ends (6) thereof in a flat (8) that is indented from an outer surface (7) of the housing, wherein in the housing (2), axially beneath the roller (5), means (9) are provided for an at least indirect bearing of a tappet follower member. The housing (2) is formed of an extruded profile having profiling on the inner surface (10) of the housing (2), wherein, viewed in a circumferential direction of the housing (2), at least two thick-wall profile segments and two thin-wall profile segments (11, 12) are present. The thick-wall profile segments lie diametrically opposite each other and the thin-wall profile segments lie diametrically opposite each other, and the flat portions (8) are located in the thick-wall profiled segments (11).Type: ApplicationFiled: January 20, 2014Publication date: December 17, 2015Applicant: Schaeffler Technologies AG & Co. KGInventors: Stefan Dorn, Nobert Geyer

Publication number: 20150361937Abstract: The invention relates to a plunger (1) for a fuel injection pump, comprising a housing (2) that has a drive-side annular end face (3) at which two flat sections (5), recessed in relation to an outer shell (4) of the housing (2), lie diametrically opposite one another, a bolt (7) that supports a roller (6) being mounted in said sections.Type: ApplicationFiled: November 18, 2013Publication date: December 17, 2015Applicant: Schaeffler Technologies AG & Co. KGInventors: Nobert Geyer, Stefan Dorn

Publication number: 20100229812Abstract: A tappet (1), either for a high-pressure fuel pump or for a valve train of an internal combustion engine, with a housing (2) whose driven side (3) used for a contact of a tappet-following part forms a contact on a bottom side (4) of a bridge part (6) projecting through an inner casing (5) of the housing (2). An anti-rotation locking device (10) projects past the outer casing (8) of the housing with a first cylinder section (9) and sits in a window (7) of the housing (2), with this anti-rotation locking device (10) being provided as a cylindrical element, and tab-like projections (13) project from peripheral walls (11) of the window (7) and the anti-rotation locking device (10), standing “loose” in the window (7), snaps behind these projections.Type: ApplicationFiled: March 15, 2010Publication date: September 16, 2010Applicant: SCHAEFFLER TECHNOLOGIES GMBH & CO. KGInventors: Stefan Dorn, Nobert Geyer, Karsten Kucht

Publication number: 20090145391Abstract: The invention proposes a switching element (1) for a valve train of an internal combustion engine, particularly for valve deactivation, with a simple-to-implement measure for adjusting the coupling lash of its coupling means (8) in a receptacle (6) using two retaining rings (19, 20), one of which is stocked in a variety of thicknesses.Type: ApplicationFiled: November 17, 2008Publication date: June 11, 2009Inventors: NOBERT GEYER, Peter Sailer, Oliver Schnell

Publication number: 20060219199Abstract: A switch element (1) is proposed for valve shut-off, fabricated as cam follower for a plunger rod valve drive of an internal combustion engine, having an outer part (2) and an inner element (4) axially movable in its bore (3) and with rotational security (15) relative to the guided inner element (4). The outer part (2), inside the bore (3), has an annular groove (6), and the inner element (4) has a radial bore (7) with two diametrically opposed pistons (8), which to couple the elements (2, 4) in their axially remote relative position achieved by a lost-motion spring (5) are displaceable towards the annular groove (6). On their cam-side under side, emanating from their radially outward, bulbous face, the pistons (8) segmentwise comprise a plane transverse surface as contact area for a facing under side (27) of the annular groove (6). The latter is intersected by two diametrically opposed oil ports (11) running offset 90° from the pistons (8) in circumferential direction.Type: ApplicationFiled: April 13, 2006Publication date: October 5, 2006Applicant: INA-SCHAEFFLER KGInventors: Nobert Geyer, Peter Sailer, Oliver Schnell
