A motion conversion apparatus has been granted a patent (Publication Number: US11920475B2) that comprises a rodrack assembly with a gearshaft member designed to produce reciprocating linear motion along a specific direction through rotational motion. The gearshaft member includes a guiding surface arrangement to interact with guide members and a second gear connection member that engages with the first gear connection member. The apparatus ensures that one revolution of the gearshaft member results in a single period of reciprocating linear motion of the rodrack assembly, with the guiding surface arrangement contacting one of the guide members at the endpoint of the motion.

Furthermore, the patent includes claims related to the engagement of the second gear connection member with the opposing engaging arrangements, the structure of the guide members, and the configuration of the gearshaft member. The apparatus is designed to maintain a constant linear speed during the reciprocating motion, with additional features such as the location of the first gear connection member between opposing pistons and the inclusion of rails for displacement. The patent also covers a pump assembly incorporating the motion conversion apparatus, with pumping members coupled to the rodrack assembly to facilitate reciprocating linear motion, driven by a motor rotating the gearshaft member.
