Abstract
Изобретение позвол ет повысить надежность и упростить конструкцию двигател . Запорный орган 13 клапана выполнен в виде плундера с дроссельными отверсти ми 14 и размещен в полости 11 поршневого пальца 4 с возможностью перекрыти маслоподвод ще- го канала 9. Термочувствительный элемент клапана выполнен в виде биме- талличесой пластины 12, установленной между запорным органом 13 и заглушкой 5 поршневого пальца. Момент подачи масла на охлаждение поршн регулируетс запорным органом через пластину 12 в зависимости от т-ры масла в маслопрдвод щем канале 8, в шатуне 3 и в полости 11. 1 ил. / с 3 сл JCO 00The invention allows to increase the reliability and simplify the design of the engine. The valve closure body 13 is made in the form of a plunder with choke holes 14 and is placed in the cavity 11 of the piston pin 4 with the possibility of blocking the oil feed of the bore channel 9. The temperature-sensitive element of the valve is made in the form of a bimetal plate 12 installed between the closure body 13 and the cap 5 piston pin. The moment of supplying the oil for cooling the piston is controlled by the locking member through the plate 12, depending on the temperature of the oil in the oil masking channel 8, in the connecting rod 3 and in the cavity 11. 1 sludge. / s 3 cl JCO 00
Description
