Description
Изобретение относитс к двигателестроению , в частности, к свободнопоршневым машинам .FIELD OF THE INVENTION The invention relates to engine-building, in particular, to free-piston machines.
Известна свободнопоршнева машина, содержаща размещенные в оппозитных цилиндрах поршни, соединенные между собой штоком, вал, св занный со штоком посредством муфты свободного хода, и топливный насос с приводом 1.A free piston machine is known, comprising pistons arranged in opposed cylinders connected by a rod, a shaft connected to the rod by means of a one-way clutch, and a fuel pump with drive 1.
В известной машине сложно регулировать подачу топлива при изменении нагрузки , что снижает эффективность работы машины на переходных режимах. In a known machine, it is difficult to regulate the flow of fuel when the load changes, which reduces the efficiency of the machine during transients.
Цель изобретени - повышение эффективности работы свободнопорщневой машины во всем диапазоне режимов путем изменени подачи топлива в зависимости от нагрузки на поршни.The purpose of the invention is to increase the efficiency of the free-flush machine in the entire range of modes by changing the fuel supply depending on the load on the pistons.
Это достигаетс тем, что привод топливного насоса выполнен в виде шарнирной т ги с роликами, взаимодействующими с профилированной поверхностью штока, а последний соединен с поршн ми с помощью упругих элементов.This is achieved by the fact that the drive of the fuel pump is made in the form of a swivel rod with rollers interacting with the profiled surface of the rod, and the latter is connected to the pistons by means of elastic elements.
На чертеже изображена описываема машина.The drawing shows the described machine.
В позитивных рабочих цилиндрах 1 размещ-ены рабочие поршни 2, соединенные между собой попарно штоком 3. На штоке 3 выполнена зубчата рейка 4, вход ща в зацепление с шестерней 5 муфты 6 свободного хода, установленной на валу 7.In the positive working cylinders 1, the working pistons 2 are placed, interconnected in pairs by a rod 3. On the rod 3 there is a cogged rail 4, which engages with the gear 5 of the one-way clutch 6 mounted on the shaft 7.
Шток 3 соедин етс с поршн ми 2 с помощью упругих элементов 8. На щтоке 3 выполнена профилированна поверхность 9, с которой взаимодействуют ролики 10 шарнирной т ги 11 дл привода топливного наcoca 12.The rod 3 is connected to the pistons 2 by means of elastic elements 8. The brush 3 has a profiled surface 9 with which the rollers 10 of the hinge rod 11 interact to drive the fuel pump 12.
Дл подачи воздуха в рабочие цилиндры 1 служит поршневой компрессор 13, поршни 14 которого св заны с муфтой свободного хода 6 так же, как и рабочие поршни 2.In order to supply air to the working cylinders 1, a piston compressor 13 serves, the pistons 14 of which are connected to the free-wheeling clutch 6 in the same way as the working pistons 2.
При работе свободнопоршневой машины возвратно-поступательное движение рабочих поршней 2 передаетс через шестерню 5 муфты 6 свободного хода на вал 7 и поршни 14 компрессора 13. С увеличением нагрузки на рабочие поршни 2 упругие элементы 8 сжимаютс , укорачива тем самым шток 3, который как бы обгон ет в своем движении рабочие поршн 2, и тем самым увеличивает количество подаваемого топлива в рабочие цилиндры 1, повыша мощность , развиваемую машиной.When a free piston machine is operating, the reciprocating movement of the working pistons 2 is transmitted through gear 5 of the free wheel coupling 6 to the shaft 7 and the pistons 14 of the compressor 13. As the load on the working pistons 2 increases, the elastic elements 8 are compressed, thereby shortening the rod 3 in its motion, the working pistons 2, and thereby increases the amount of fuel supplied to the working cylinders 1, increasing the power developed by the machine.
Таким образом, упругое соединение поршней со штоком в сочетании с приводом топливного насоса обеспечивает саморегулирование мошности свободнопоршневой машины .Thus, the elastic connection of the pistons with the rod in combination with the drive of the fuel pump provides self-regulation of the power of the free piston machine.
