Device for a variable actuation of the charge-cycle valves in reciprocating piston engines

摘要

Device for a variable actuation of a charge changing valves in reciprocating piston engines, consisting of a housing (g), a in the housing (g) in a first rotary joint (ng) supported cam (n), whose circumferential movement is derived from the crankshaft, a driven member (a), which in the housing (g) in a second pivot joint (ag) is clearly guided, and the motion to at least one load change valve (v), and an intermediate member (z), which in the housing (g) in a third rotary joint (zg) is clearly guided, and with the cam (n) and with the output member (a) in each case via a cam joint (zn, za) is connected, wherein the cam joint (za) between the intermediate member (z) and the driven member (a) one hand, a locking section and a control section, characterized in that the section of the cam joint (za) of a curve (kazr1) on the driven member (a) is formed, which is a circular arc whose center coincides with the center of rotation of the third rotary joint (zg) and...
