Claim 0:
1. A motion conversion apparatus comprising:
a rodrack assembly comprising a first gear connection member and two guide members, the first gear connection member comprising first and second, opposing engaging arrangements; and
a gearshaft member configured to cause reciprocating linear motion of the rodrack assembly along a reciprocation direction by rotational motion of the gearshaft member about a rotational axis,
the gearshaft member comprising a guiding surface arrangement configured to contact either one of the two guide members during the rotational motion of the gearshaft member, and a second gear connection member configured to engage with the first gear connection member during the rotational motion of the gearshaft member, the first engaging arrangement, the second engaging arrangement and the second gear connection member being coplanar, wherein within a first half of a revolution of the gearshaft member an entirety of the second gear connection member engages the first engaging arrangement and within a second half of the revolution of the gearshaft member the entirety of the second gear connection member engages the second engaging arrangement, whereby one revolution of the gearshaft member causes a single period of reciprocating linear motion of the rodrack assembly,
the guiding surface arrangement being configured to contact one of the two guide members at an endpoint of the reciprocating linear motion of the rodrack assembly.
