Patent RU-2008464-C1 (RU)
Inventor: KUTSENKO ALEKSANDR S
IPC: F02B43/08
Filed: 1989-04-26
Granted: 1994-02-28
Abstract: Изобретение относится к способам эксплуатации двигателей внутреннего сгорания, переоборудованных на питание водородом. Целью изобретения является повышение эффективности путем устранения обратных вспышек во впускном трубопроводе. Давление, под которым подают водород (В), устанавливают таким, что под действием волновых газодинамических процессов в впускном канале (ВК) к началу впуска в водородный тракт (ВТ) забрасывается воздух. Этот воздух препятствует контакту горячих продуктов сгорания в начале впуска с водородовоздушной смесью, находящейся в ВТ за воздухом. Истечение воздуха в начале впуска из ВТ в ВК обеспечивает нужную задержку подачи. Отсечка подачи В происходит до закрытия впускного клапана за счет роста давления в ВК при торможении потока воздуха в конце впуска. После отсечки подачи В продолжается последняя фаза впуска и ВК очищается потоком воздуха от В. 2 ил.

Title: Press mold for pressing powder layer onto metal disk surface
Inventor: EZRETS FEDOR A
IPC: B22F7/04
Filed: 1990-07-09
Granted: 1995-03-20
Abstract: FIELD: powder metallurgy. SUBSTANCE: press mold has working chamber defined by lower dies 1 and 2 and filled with metal powder, with metal disk- shaped ring 11 being put from top. Upper and lower parts of press mold are brought together. Pressure transmitted through upper punch 7 and lower punch 5 facilitates pressing of metal powder onto ring 11. Dies 1 and 2,3 and 4 are tightly pressed to ring 11 to define cavities, where straps are formed. Upon completion of molding process, when it only remains to compact the pressed-on layer (with punches 5 and 7 not reaching ultimate position by 0.5 mm of punch stroke), pushers 12 and 14 are actuated to release spring- loaded dies 1 and 2, 3 and 4 and, consequently, straps 13 from sides. As a result stressed straps of ring 11 are immediately expanded. Upon obtaining required sizes and density of straps, loading is released from punches 5 and 7, which are thus separated from ring 11 and straps 13. Ready product loosely lying on dies 1 and 2 is removed. EFFECT: high quality of product and enhanced reliability in operation of press mold. 1 dwg
