В ОСНОВНОМ авт. св. № 138115 описано устройство дл изменени на ходу степени сжати двигател внутреннего сгорани с противоположно движущимис поршн ми и синхронизирующей передачей из цилиндрических шестерен путем создани относительного углового сдвига между коленчатыми валами, в которых дл регулировки степени сжати двигател применен дифференциальный механизм.BASIC Auth. St. No. 138115 describes a device for changing the compression ratio of an internal combustion engine with oppositely moving pistons and a synchronizing transmission from cylindrical gears by creating a relative angular shift between the crankshafts, in which a differential mechanism is used to adjust the compression ratio of the engine.

Предлагаемое устройство отличаетс тем, что в нем применена косозуба муфта, включенна в кинематическую цепь синхронизирующей передачи. Это конструктивное изменение обеспечивает стабильность регулировки степени сжати двигател за счет плавного перемещени обода шестерни относительно ее ступицы.The proposed device is characterized in that it uses a helical coupling, included in the kinematic chain of the synchronizing transmission. This design change ensures the stability of the adjustment of the compression ratio of the engine due to the smooth movement of the gear rim relative to its hub.

На чертеже изображено предлагаемое устройство в разрезе.The drawing shows the proposed device in section.

Ступица / с наружными винтовыми Шлицами имеет внутреннее неподвижное шлицевое соединение с валом - торсионом 2, который соединен с верхним валом двигател (не показан на чертеже). Муфта 3 содержит внутренние и наружные винтовые шлицы с углом наклона к образующей 30° с противоположным углом наклона. Наружные шпицы имеют зацепление с ободом шестерни 4. Перемещение муфты 3 происходит под давлением масла и регулируетс золотником 5, который при перемещении открывает и закрывает определенные отверсти Через эти отверсти масло подаетс в полость под порщень 6 муфты 3 Изменение положени золотника 5 осуществл етс за счет вращени черв ч№ 152143- 2 -The hub / with external splines has an internal stationary spline connection with the shaft - torsion bar 2, which is connected to the upper shaft of the engine (not shown in the drawing). The clutch 3 contains internal and external screw slots with an angle of inclination to the generatrix of 30 ° with the opposite angle of inclination. The outer spitzs engage with the rim of the gear 4. The clutch 3 moves under the pressure of oil and is controlled by the spool 5, which opens and closes certain openings during the movement. Through these holes, the oil flows into the cavity under the piston 6 of the clutch 3 the worm number 152143-2 -
