Изобретение относитс  к области двигателестроени  и касаетс  гидравлических толк телей механизмов газораспределени  двигателей внутреннего сгорани .FIELD OF THE INVENTION The invention relates to the field of engine-building and concerns the hydraulic pushes of the timing mechanisms of internal combustion engines.

Известны гидравлические толкатели механизмов газораспределени  двигателей внурреннего сгорани , содержащие корпус с полы плунжером, заполненные рабочей жидкостыо, невозвратный клапан дл  перепуска рабочей зющкости в полость корпуса и п ггу под головку толкател , установленную в плунжере И .The hydraulic pushers of the mechanisms for the timing of engines for internal combustion are known, comprising a housing with a plunger floor, filled with a working fluid, a non-return valve for bypassing the working space into the housing cavity and under the plunger head installed in the plunger I.

Однако такие толкатели имеют недостаточк но устойчивые рабочие и эксплуатационные характеристики, затрудн ющие запуск двигател  при низкой температуре без предварительного его подогрева, они не автонок ны по отношению к системе смазки двига тел .However, such pushers have insufficiently stable operating and performance characteristics that impede engine start at low temperature without preheating, they are not autoconfigurable with respect to the engine lubrication system.

Целыо изобретени   вл етс  повышение стабильности устройства в работе путем обеспечени  автономности гидравлической системы толкател .The purpose of the invention is to increase the stability of the device in operation by ensuring the autonomy of the hydraulic system of the pusher.

Это достигаетс  тем, что плунжер соединен с корпусом гофрированным сильфоном This is achieved in that the plunger is connected to the body by a corrugated bellows.

  снабжен дополнительно двухстеночным сильфоном, а полости сильфонов сообщены с полостью плунжера.provided with an additional double wall bellows, and the bellows cavity communicated with the plunger cavity.

На чертою показан предложенный гидравлический толкатель, продольный разрез. . Толкатель имеет цилиндрический корпус 1 с конусообразным дном и отверстием, ко торое закрыто пробкой 2, В полость 3 корпуса помещен полый плунжер 4, в лолость 5 которого выход т окна iJ и канал, н&возвратного клапана 8. Плунжер подпружинен относительно дна корпуса пружиной 9, Корпус толкател  герметично сопр жен с плунжером посредством гофрированного 10,  вл ющегос  компенсатором предельного перемеи ени  плунжера. На плу№жере установлен второй гофрированный двухи стеночный сильфон 11, образующий замкнутую кольцевую полость 12 измен емого объема, сообщенную с полостью плунжера окнами 13. Наруж 1а  образующа  второго сильфона герметично сопр жена с плунже ром, а внутренн   - с его п той 14, в которой образована полость 15 под гсшовку толкающей вту кн механизма газораспредвThe line shows the proposed hydraulic plunger, a longitudinal section. . The pusher has a cylindrical body 1 with a cone-shaped bottom and a hole that is closed by a stopper 2, a hollow plunger 4 is placed into the cavity 3 of the housing, into the hollow 5 of which there are windows IJ and a channel, n & a return valve 8. The plunger is spring-loaded relative to the bottom of the body by a spring 9 The body of the pusher is hermetically coupled to the plunger by means of a corrugated 10, which is the compensator of the maximum displacement of the plunger. A second corrugated two-wall bellows 11 is installed on the harvester, forming a closed annular cavity 12 of variable volume, connected to the plunger cavity by windows 13. The outer 1a forming the second bellows is tightly joined with the plunger, and which formed the cavity 15 under gsshovku pushing vtu kn gas distribution mechanism
