Critical Workings of the Venus 2000 Receiver

It is quite important to understand exactly how the Venus 2000 receiver works. A lot is made of its "hands off" mode of operation. This is only one way the receiver can be used, but it is certainly the most unique among sex toys for men.

The power unit supplies alternating air pressure and vacuum. This goes into an air space on the receiver that is sealed. One wall of this sealed space is the rigid receiver housing. The other wall is the latex liner. As the pressure fluctuates, it compresses or expands the latex liner. The liner pulses in size. The total trapped air volume can be adjusted with what is called the "stroke control hose". This adjustment can cause the liner to go from fully expanded by vacuum and nearly filling the rigid receiver housing, to being quite collapsed by pressure and trying to balloon out the ends. A irrigation syringe can be fitted to the stroke control hose to allow for very fine and specific control of the trapped volume of air in the sealed system.

The basic idea is that when the penis is lubricated and inserted into this pulsing latex liner, it will be alternately sucked into and expelled out of the liner to some extent determined by the exact trapped air volume. The receiver will ride up and down the length of the erect penis if the receiver can move freely.

A wide range of liner material widths is available to customize the fit of the receiver. Note that the liner material is specified for sale by its flat width. This means that when it is formed into a tube as it is installed on the receiver, it will produce a considerably smaller tubular tunnel as demonstrated by the chart. This is of course a relaxed tubular size, without and stretch or vacuum pulled on it.

In order for this system to work there is one very critical consideration. Air trapped in the sealed system, represented by the internal capacity of the power unit diaphragm pump, the hose, and the receiver volume between the rigid housing and the liner material is good. It is the working air volume of the system. Air trapped inside the liner tunnel of the receiver, is BAD!

Air trapped inside the receiver liner tunnel will also be sucked in and expelled out as the liner contracts and expands. If the penis tries to share the liner tunnel with THIS bad trapped air, it will be summarily expelled, spit out. The receiver will pop off. Not to put too fine a point on it, but the receiver is not what is supposed to "pop off".

In the early days there was a required procedure to deal with this problem. You needed to use the stroke control hose to build up the good trapped air volume until you had the liner completely collapsed, forcing out all the air you could from the liner tunnel, and then pressing the end of the penis against the receiver opening, allow the air volume to normalize, sucking the lubricated penis into the interior of the liner tunnel without any trapped bad air. This was important because the receiver caps had no one way valves. This procedure still works.

But the revolution in ease of use came when the one way valves were added to the caps. Now trapped air could be expelled out the end cap as the penis is inserted in the other end. This is why a properly working valve on the end cap, and rinsing and scrubbing the valve after each use is so important. The system is not perfect. Lubrication loves these valves and will almost immediate seek them out and try to clog them. Usually the valves will just clear themselves in use if a bit of lubrication gets into them.

An interesting modification of the receiver can be made using a baby bottle nipple to make a barrier to help prevent lubricant from getting into the valves in use. This will be described later.

This brings us to the final, super critical part of the receiver. The entrance. While the cap and its valve is critical to the operation of the receiver, it pales in comparison with the constrictor, the structure designed to allow the penis to enter, and slide back and forth, but prevent entrance of air into the liner tunnel during use.

Originally this was a special annular piece of firm foam rubber that was inserted into the receiver between the rigid receiver housing and the liner material at the entrance end. Its purpose was to make the critical seal around the shaft of the penis. Not too firm, or no sliding would happen. Not too loose or instead of the penis being sucked into the receiver, a shot of air would be sucked in around it. If it is a big enough shot of air, even the valve can not vent it in time and once again the receiver pops off.

So herein lies the rub. The liner needs to be quite active, expanding and contracting, sucking and squeezing out, changing size and shape in a rhythmic fashion. BUT! The receiver entrance, the open end of the receiver, needs to be relatively inactive, with a proper adaptive snug seal around the shaft of the erection, even as the penis changes size and shape with level of excitement and the receiver slides back and forth.

This is the job of the constrictor and the other tricks aimed at making essentially two areas in the receiver liner. An entrance which does not flex a lot and provides a snug seal, and a quite active area which is capable of expanding and contracting a lot. This is the key, realizing there are two areas on a receiver liner, the active area and the seal area.

With the bad air vent valve in the receiver cap, Abco brilliantly solved one pressing problem and made the Venus system completely practical. You can argue the merits of the one and two valve caps. I am undecided. The two valves can vent faster, but also gum up twice as much, need twice as much cleaning and also have twice the chance to stick and leak.

The final problem is solved by fitting of the receiver, and particularly the design of the constrictor and entrance area relative to the active liner area.

While factory supplied complete receivers are fully functional and if ordered carefully relative to erection size are quite satisfactory, I have found that personal fitting is the final frontier for getting the most out of your Venus 2000 system.

So much of the detailed discussion will focus on this one area, the open end of the receiver, and its associated constrictor. Trust me. Get this right and Venus 2000 will do everything claimed for it and more. I suspect you will end up with several receiver housings and a supply of liner material, creating several different favorite receiver configurations.
