Rotary swing piston engine - has pistons which perform working stroke with each rotation of driving drum

摘要

The engine housing consists of a fixed outer casing (1) with coolant and lubricant ducts (2), front and rear bearing covers (7,8) and suction and discharge ports contains working and transmission units. The former comprises a driving drum, outer bearing plate (13) with drive shaft extension (14) and an internal bearing box (15) with cylindrical bores for swing arms with working cylinders, each having a piston with a fixed rod (38) connected to a swing shaft (20). The transmission casing (16) is fixed to the bearing box (15) and has an outer bearing plate (17) with a driven shaft extension (18) housing a drive gear (31) and two idler gears (32), one of which meshes with an internal ring gear (33) on the outer casing (1) and is connected to the swing shaft (20). USE/ADVANTAGE - A quiet, economical piston engine for vehicles and fixed installations. It is easy to assemble, operates without no valves, and is more compact and efficient conventional four stroke engines.
