ABSTRACT:
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).
