ECCENTRIC PUMP/COMPRESSOR
The next five images show the sequence of rotation and the cylinder and how it
causes the advancement and retraction of the piston, as the slot in the piston
Must find a new axial position against the center pin which is stationary.
Larger chamber
facing Side 1 of
Piston due to
full retraction
Complete Seal
Stationary
Outer Housing
The full stroke of
the piston is twice
the distance
between the center
of rotation of the
Rotating Cylinder
and the center of
the Stationary Pin
Stationary Pin,
can be connected
to the Stationary
Outer Housing
Piston
Smaller Chamber facing
Side 2 of Piston due to
full advance
Rotating
Cylinder
Complete Seal
20 degrees of CCW rotation
Outlet port is now
connected to the
advancing side of
the piston
Inlet is connected
to the retracting
side of the piston
180 degrees of CCW rotation
Large chamber is now facing
the Side 2 of Piston due to
full retraction and intake of
low pressure gas
Side 1 of the piston is now
facing the small chamber due
to full advance and the
compressed gas was delivered
to Outlet just before reaching
this full seal position
Complete Seal
270 degrees of CCW rotation
Chamber
volumes are
equal at 90
degrees and
270 degree
rotations
290 degree rotation, on the way to 360 and starting the same cycle
Chamber
facing
Side1 is
getting
larger again
Chamber facing Side2
getting smaller by the
same amount that the
other chamber is
getting larger
A pump based on the same movement cycle, but with three
staggered pistons
This Cap is

Pump is driven
by this shaft,
