<p>A linear pump has a motor with a gear that converts the rotary motion into linear motion. A non-rotating cylindrical linear slide (26) is coupled to the pump rod (36, 38) and located within a housing (12, 14). The slide (26) is surrounded by a freely rotating bush (13) within the housing. The bush is coupled to a coaxial cog that engages with a pinion gear on the motor shaft.</p> |
