Venus 2000

Venus 2000 is a sexual stimulation tool for men. It is a self-actuated masturbation aid with controllable strokes. The machine works with or without an erection.

The device was marketed as Venus II from October 1993 to April 1998. With the assistance of Val, a Russian engineer, the Venus II was invented by Rick Gellert, President of 3S Corp. Gellert has previously written:

...It seems male desire for sexual activity ranges from needing an orgasm once in many weeks to wanting several in a day. [...] after hundreds of variations, I developed a product unique enough so that I was awarded patent #5501650.

Rick and Val presented their new device to Abco Research Associates in 1993 (also manufacturer of the Sybian), and Abco helped them launch and market it. As a result, Abco became the primary marketer of the Venus II. In April 1997, Abco purchased the Venus II patent along with all manufacturing and marketibng rights. This led to the launch of an improved version, Venus 2000.

In 2014 Abco modified the name of the product to Venus by Sybian. They also refer to the product as Venus For Men.

The Venus 2000 consists of a main box linked to a cylindrical "receiver" that fits over the penis by a connecting hose. The "receiver" superficially resembles the teat cup of a milking machine, and contains an inner and outer chamber separated by a cylindrical flexible rubber liner. Only the outer chamber is linked to the main box, with the inner chamber open to the air at one end, and blocked at the other end by a cap that contains a one-way valve that leads to the open air.

The main box contains a gearmotor which drives a reciprocating diaphragm. Air moves to and from the outer chamber of the "receiver" via the hose. The device works by sucking in the shaft of the user's penis when the tip is placed against the Venus 2000's opening before activation, using the partial vacuum created by the removal of air from the inner liner via the one-way valve at the closed end of the receiver. The amount of air in the system is adjustable and determines the stroke length. Most men can adjust it to move the full length of the shaft. A significant amount of personal lubricant is needed to be added within the liner for the machine to operate correctly.

The system is controlled during operation by two small control boxes. One of them is an electrical control box, with a speed adjustment knob, attached to the main box by an electrical cable. The other is a pneumatic control box, linked by a rubber tube to the diaphragm chamber, and has two push-buttons, one to add air to the system, and the other to remove air from the system. The final adjustment possible is an internal adjustment that can be used to change the amplitude of the pumping motion, but this is not available in operation, as adjusting it requires the main box of the machine to be dismantled and reassembled.
