  • - der Strahl (5) seitlich auf den Nocken (6) in einen der Öffnungsflanke (10) des Nockens (6) in Drehrichtung vorgelagerten Bereich (11) des Grundkreises (12) gesteuert gerichtet ist,
dadurch gekennzeichnet,
  • - dass die Spritznut (4) in einem die Nockenwelle (7) aufnehmenden Lager (13) angeordnet ist, und
  • - mit dem Schmiersystem über eine in einem Lagerbund (14) der Nockenwelle (7) vorgesehene Abschnitts-Umfangsnut (15) gesteuert zeitweise verbindbar ist, wobei
  • - der Nocken (6) an seiner der Spritznut (4) zugewandten Seite im Be­ reich (11) des Grundkreises (12) vor der Öffnungsflanke (10) eine zur Kontaktfläche (16) des Übertragungselementes (9) offene Schmieröl- Auffang- und Verteil-Tasche (17) aufweist.
1. Device for intermittent spray lubrication for a valve train of an internal combustion engine,
  • - In the in a camshaft bearing ( 3 ) a controlled temporarily connectable with a machine lubrication system spray groove ( 4 ) is seen before to deliver a lubricating oil jet ( 5 ) on co-operating contact surfaces of a cam ( 6 ) of a camshaft ( 7 ) and one on a gas exchange valve ( 8 ) acting transmission element ( 9 ), wherein
  • - The jet ( 5 ) is directed laterally onto the cam ( 6 ) into a region ( 11 ) of the base circle ( 12 ) upstream of the opening flank ( 10 ) of the cam ( 6 ) in the direction of rotation,
characterized by
  • - That the spray groove ( 4 ) is arranged in a bearing ( 13 ) receiving the camshaft ( 7 ), and
  • - Can be temporarily connected to the lubrication system via a section circumferential groove ( 15 ) provided in a bearing collar ( 14 ) of the camshaft ( 7 ), wherein
  • - The cam ( 6 ) on its side facing the injection groove ( 4 ) in the loading area ( 11 ) of the base circle ( 12 ) in front of the opening flank ( 10 ) one of the contact surface ( 16 ) of the transmission element ( 9 ) open lubricating oil collection and distribution Pocket ( 17 ).
2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet,
  • - dass bei einem Schlepphebel (19) als Übertragungselement (9) der Nocken (6) - in Drehrichtung gesehen - vor der Auffang- und Verteil- Tasche (17) seitlich einwärts angeschrägt ist (Anschrägung 20), und
  • - dass der Schlepphebel (19) im Bereich der Einwirkung auf einen Schaft (21) des Gaswechselventils (8) eine seitlich angeordnete Schmieröl-Zulaufrinne (22) aufweist.
2. Device according to claim 1, characterized in that
  • - That with a rocker arm ( 19 ) as a transmission element ( 9 ) of the cams ( 6 ) - seen in the direction of rotation - in front of the collection and distribution pocket ( 17 ) is chamfered laterally inwards (chamfer 20 ), and
  • - That the rocker arm ( 19 ) in the area of action on a shaft ( 21 ) of the gas exchange valve ( 8 ) has a laterally arranged lubricating oil feed channel ( 22 ).
3. Vorrichtung nach Anspruch 1 und 2, dadurch gekennzeichnet, dass die zur Nockenwelle (7) im wesentlich parallel angeordnete Spritznut (4) über die Abschnitts-Umfangsnut (15) mit einem im Lager (13) endenden Ver­ sorgungskanal (18) verbindbar ist.3. Device according to claim 1 and 2, characterized in that the to the camshaft ( 7 ) arranged substantially parallel spray groove ( 4 ) via the section circumferential groove ( 15 ) with a in the bearing ( 13 ) ending Ver supply channel ( 18 ) can be connected . 4. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die zur Nockenwelle (7) im wesentlich parallel angeordnete Spritznut (4) über die Abschnitts-Umfangsnut (15) mit einer im Nockenwellen-Lagerbund (14) einer hohlen, schmierölführenden Nockenwelle (7) vorgesehenen Radialbohrung (23) verbindbar ist.4. Apparatus according to claim 1 or 2, characterized in that the spray groove ( 4 ) arranged essentially parallel to the camshaft ( 7 ) via the section circumferential groove ( 15 ) with a hollow cam oil-bearing camshaft in the camshaft bearing collar ( 14 ) ( 7 ) provided radial bore ( 23 ) can be connected.
