Detailed Closeups of Inside the Venus 2000 Power Unit

Here we see the diaphragm on the left with its push rod attached to the drive wheel. You can just see the adjustment screw on the large hose clamp that holds the diaphragm in the upper left hand corner. Note the several threaded holes on the aluminum drive wheel into which the pushrod can be mounted. Behind the drive wheel is the gear housing of the powerful DC industrial motor that runs the entire thing, a big step forward from the windshield wiper motor that powered the first prototype according to company lore.

The present one is either a 10:1 or 15:1 Bodine right angle drive, gear head DC motor, a very powerful motor especially after the gear reduction. In the closer photo below you can see the brass bushing inside the loop of the drive rod. Some wheel bearing grease inside this brass bushing might be added at infrequent intervals, or when you change the mechanical stroke length adjustment setting.

On the front is the motor control board, which if powered up can contain dangerous voltages both DC and AC. While I am not recommending you fiddle with these, you can see the two potentiometers that control the minimum and maximum speed range under the drive wheel in this closer picture. They are electrically above and below the control pot whose wires mount in the three screw terminal strip in the middle. These are set at the factory, and I found only a slight optimization was possible over factory settings, not worth the effort in my opinion. Also it is quite risky if you do not know exactly what you are doing!
