A motion converter mechanism to be interposed between a driving device and a driven device to provide a rotary motion in one device and a reciprocatory motion in the other device, including a housing (11, 13); a reciprocatory member (40) mounted for reciprocatory movement along a longitudinal axis and having a first end coupleable to one of the devices; a rotary member (22) mounted for rotary movement about a rotary axis and coupleable to the other of the devices; and crank arm (50) having a first end pivotally coupled to the rotary member and a second end pivotally coupled to the reciprocatory member; and an alignment member (52) extending transversely of the longitudinal axis and having a first end pivotally coupled to the reciprocatory member and a second end pivotally coupled to the housing such as to maintain the reciprocatory member in general coaxial alignment with the longitudinal axis, and thereby substantially to prevent side loading of the reciprocatory member during its reciprocatory movements. |
