OSCILLATING PISTON ENGINE ANP ITS CONVERSION MECHANISM

摘要

The invention relates to a conversion mechanism for an internal combustion (11 ) engine. The conversion mechanism is operable to convert pivotally reciprocating motion of an output member (30) about a prime pivot axis (30.1 ) into rotational motion of an output shaft (40) about a rotational output axis (40.1 ). The conversion mechanism includes a cam housing (74) which is fast with the output member (30) for movement about the prime pivot axis (30.1 ) and which is pivotally displaceable relative to the output member (30) about a cam axis (74.1 ) which is transverse to the prime pivot axis (30.1 ), the cam axis (74.1 ) being movable with the output member (30) about the prime pivot axis (30.1 ), the cam housing (74) defining at least one cam member (86); and a cam follower (80) on the output shaft (40), the cam follower (80) having a wobble axis (80.1 ) which is titled or inclined relative to the rotational output axis (40.1 ).
