PISTON ENGINE AND AN ENGINE DEVICE COMPRISING THE SAME

摘要

The disclosure relates to a rotary piston, a piston engine comprising the rotary piston, and an engine device comprising the piston engine. The rotary piston comprises a piston body having a triangular vertical cross-section, mutually engaged large and small planetary gears fixed at the middle of the piston body, and a crankshaft running through the small planetary gear. The three angles of the triangular cross-section extend outwards to form protruded ends. The two sides of each protruded end form a compression groove and a combustion groove, respectively. The piston engine of the present disclosure comprises a shell, a crankshaft in the shell and two sets of rotary pistons, wherein the crankshaft has two ends and the two sets of rotary pistons are positioned symmetrically at the two ends of the crankshaft and separated by a holder positioned between the two sets of pistons.

主权项

1. A rotary piston, comprising
a piston body having a triangular vertical cross-section, mutually engaged large and small planetary gears fixed at the middle of the piston body, and a crankshaft running through the small planetary gear, wherein the three angles of the triangular cross-section extend outwards to form protruded ends with a 120-degree angle between adjacent protruded ends, and the two sides of each protruded end form a compression groove and a combustion groove, respectively.
