<p>A mechanism is disclosed for interconnecting a rotary component (32) and two members (25, 26) linearly reciprocable at 90° to each other in respective bores (16, 18, 17, 19) in a housing (15). The first rotary component (32) has a shaft (33) with an eccentric surface (34). A second rotary component (36) has a bore (37) in which is received surface (34), and first and second eccentric surfaces (37 and 38), the eccentric surfaces (34, 37 and 38) all having the same throw. Each reciprocable member (25) has a pair of spaced-apart pistons (26, 27) with a web (28) extending therebetween, the web having a bore (29) in which is received the first (or second) eccentric surface (38 or 39). In operation, the first and second rotary components (32 and 36) contra-rotate, and the first and second members (25) reciprocate linearly 90° out of phase with each other.</p> |
