摘要： The present invention relates to an oil scraper ring spring (1) for an oil scraper ring (3) comprising the oil scraper ring spring (1), an upper and a lower metal ring (21, 22) and provided for being mounted in an oil ring groove of a piston. The oil scraper ring spring (1) comprises a plurality of upper regions (5) and a plurality of lower regions (7) arranged in alternating manner in a circumferential direction so as to be spaced in an axial direction; connecting regions (9) each connecting the adjacent upper and lower regions (5, 7) to each other. Each of the upper and lower regions (5, 7) comprises: a nose section (13) disposed at the inner circumferential end and adapted to push the respectively abutting upper or lower metal ring (21, 22) radially outwardly, and having a through-opening (15); an abutment section (17) extending radially between the nose section (13) and the outer circumferential end and configured to have the respective upper metal ring (21) abutting thereon or the respective lower metal ring (22) abutting thereon; wherein the abutment section (17) has a recess (19) formed therein the depth of which, relative to the abutting area of the abutment section (17), increases in the radial direction towards the through-opening (15), and the width of which increases in the radial direction towards the through-opening (15); wherein the recess (19) in the abutment section (17) has substantially the shape of a half-funnel; wherein the half-funnel has an opening angle of 30° to 150°, in particular of 30° to 60°, or wherein the upper side edges of the recess (19) span an angular segment of 5-50°, in particular 5-15°; and wherein increasing the depth and width of the recess (19) radially inwardly together with the through-opening (15) serves to increase and accelerate the oil flow to the piston center.

摘要： An actuating device includes an exhaust flap of a supercharging pressure control of turbocharged internal combustion engines. The exhaust flap is arranged pivotably in an exhaust pipe, in particular in the housing of a turbine of an exhaust-gas turbocharger, and controls in dependence on the compressor-side supercharging pressure the opening cross section of a bypass line which circumvents the turbine. The exhaust flap is arranged on an actuator arm which is fastened on a shaft mounted rotatably in the exhaust pipe and adjustable from outside the exhaust pipe via an adjustment lever and a control rod which is articulated thereto and via a linear control motor. In order to avoid vibration-induced buzzing noise in the actuating device, a friction damper is connected into the force flow between the shaft and the control rod, in particular for system damping in the region of the exhaust flap.
