Uncoupled rotary linear pump |
摘要 |
A fluid pump includes a piston mounted in a housing. A check valve is disposed in the piston for controlling fluid flow. A linear motor joins the piston and housing for axial oscillation of the piston to pump the fluid in unidirectional flow. A rotary motor includes magnet strips mounted in the piston and a cooperating rotary drive coil mounted in the housing. The rotary motor is magnetically uncoupled from the linear motor.
