COMBINATION PNEUMATIC AND ELECTRIC LINEAR ACTUATOR

摘要

A linear actuator system can move a probe along a substantially linear path The linear actuator system can have a housing with a magnet mounted in the housing creating a magnetic field An electric coil piston can be slidably mounted in the housing The coil piston can have a coil for carrying a current and can be disposed for translational movement within the magnetic field in response to current flow through the coil The probe can be attached to the coil for translational movement with the coil In addition, a pneumatic cylinder can be connected to the piston configured to apply a force to the piston in response to an activation of the pneumatic cylinder
