Pump Technology
The Linear-motor-driven
Free Piston System (Pat.) has
an internal piston inside the
cylinder which is driven by an
electro-magnet and spring system
controlled by the alternating
input current cycle.
The piston thus forms a single
combined structure of two usually
different devices; motor and pump.
The system is quiet and vibration
free, and offers the advantages
of easy maintenance and a long
operating life.
Linear Pump Operating Principle
The activated
electro-magnet attracts the piston
against the return spring, while
air is taken into the cylinder
through the opened inlet valve.
When the electro-magnet is deactivated,
the return spring pushes the piston
back, and the compressed air is
brought out of the cylinder through
the now open outlet valve. The
system can function as either
an air compressor or as a vacuum
pump.
Fewer Components
The pump's unique
and simple structure has no complicated
transmission mechanism such as
a crankshaft, connecting rods,
ball bearings, etc., which are
widely used in between the motor
and compressor in conventional
pumps. |
