Regulating slide-valve gear

摘要

A regulating slide-valve gear, especially for an asymmetrical timing of two-stroke engine. In the regulating slide-valve gear a driving element of an epicyclic gear (1) engages the engine crankshaft and at the same time via a controlled element (4) a driven element of the epicyclic gear (1) which is connected by a gearing with at least one slide-valve shaft (6) of a turning slide valve (7) mounted rotatable within a slide-valve housing (8) arranged in the engine port (C). The controlled element (4) of the epicyclic gear (1) is connected to a regulating element of a control device (3) the electrical input of which is connected with a sensing and regulating unit (2) established for sensing actual parameters of the engine and regulating mutual angular positions of the engine crankshaft and the timing edge of the turning slide valve (7). The advantage of the regulating slide-valve gear according to the invention is the possibility of continuous regulation of the optimum conditions of port timing in respect of actual parameters of the running two-stroke engine. The advantage of the arrangement of the turning slide valve (7) with two coaxial carried and counterrotating disks consists in the velocity of closing or opening the engine port (C).
