Each pressure piston (3) moves relative to the housing in an axial direction in a separate guide (4) in the housing (2), and also has a support (6) for an at least indirect contact with the corresponding gas-exchange valve on a distal end (5) away from the housing, and a non-return valve (8) in the region of a housing bottom (7) wherein a separate high-pressure chamber (9) is associated with each pressure piston (3) in which the non-return valve (8) opens. The high-pressure chamber (9) extends axially between the bottom (7) of the pressure piston (3) and a base (10) of the housing (2), and the pressure pistons (3) arranged in the common housing (2) have a common reservoir.

Abstract: A switchable valve train for gas-exchange valves of internal combustion engines with a rocker arm device (1), in which a rocking motion about a rocker arm axis (3) can be introduced by at least one cam (2a, 2b), one tappet, or the like, wherein this rocking motion can be transmitted to at least one valve (4). The rocker arm device (1) is formed from at least one cam lever part (5) in working connection with the cam (2) and a valve lever part (6) in working connection with the valve (4), which are supported so that they can rock about the rocker arm axis (3). A coupling device is constructed between the cam lever part (5) and the valve lever part (6), in order to selectively engage and disengage the transmission of the rocking motion.

Abstract: The finger follower has an inner and outer body and a torsional lost motion spring positioned at its lash adjuster end of the outer body. The torsional lost motion springs have a short leg that abuts the outer body and a long leg that contacts the inner body. The torsional spring is located above the pivot point of the finger follower so as to provide a low mass moment of inertia and to reduce the weight over the valve stem end of the follower.
