Thank you for your patience, guys. Enjoy
It seems quite hard to believe, but the Ego9 is the 5th Generation of Eclipse Ego. Few would have thought, back in 2004, that the first Eclipse Ego would have had such wide-spread and immediate impact across the globe as it has had. And yet here we are with the Ego9. The latest incarnation of the most popular tournament marker in the world.
The Eclipse Ego has always been built around the solid foundations of Reliability, Performance, Light-Weight and Simplicity. And the Ego9 is no exception. In fact, it is obvious from the outset that the ground-up re-working of the Ego platform that was required in the development of the Ego9 was undertaken with the sole purpose of improving on every one of those key areas. Reliability has been improved by removing potential weak areas of the previous design but without sacrificing any performance. In fact performance in almost every area has been increased substantially over the previous generation of Ego. And though there have been additions of new elements to items such as the S3 Self Purging In-Line Regulator and the body lengthened in order to incorporate a larger valve chamber, the weight of the marker has not increased by a single ounce over the outgoing model. It is clear that compromise was not a consideration in the design and implementation of the Ego9. And for that reason alone, it makes the Ego9 simply the best Ego ever.
The Ego9 has brought along a completely new design philosophy for the key elements of the electro-pneumatic assembly. A completely new custom solenoid valve has been designed and engineered to give the absolute maximum performance possible from the rammer mechanism, but in a package that is both smaller and far simpler to maintain than any previous Ego solenoid valve.
The main difference from any previous generation Ego is that there are no longer any QEVs. But the only way it has been possible to remove the QEVs and yet still increase cyclic speed and performance, has been to design and produce a brand-new, bespoke solenoid valve, and mount it and port it directly into the rammer chamber. By designing the solenoid from the ground-up, rather than trying to shoe-horn in an off-the-shelf item, it has meant that we have been able to design the housing to both fit in as small and compact profile as possible, and also port the valve for the absolute maximum performance in terms or response time and flow rate. And because the valve is ported so close to the rammer chamber, the actual exhaust paths through the valve are larger, shorter and less convoluted than any of the previous generation QEVs. And we all know from experience that it is the exhaust paths that can have the most striking effect on rammer speed and efficiency.
There are also several other benefits of the new solenoid valve. For example, by designing it and mounting it in such a way there is no longer any need for hoses from the solenoid valve to the QEV block or ports. There is now just one hose (that has been increased in flow by 2.5 times over the original supply hose) that runs from the LPR Torpedo down to the new solenoid valve.
The new solenoid valve has also been designed to be very user-friendly and user serviceable. The same size hex key that removes the eye covers and the grips can also be used to remove and 100% strip-down the new valve. And with so-few components, trouble-shooting and repair (if it is ever needed!) could not be any easier.
And if all that wasn’t enough, the new solenoid valve not only operates with a 40% lower Wattage power coil, but because the speed of the rammer has been so significantly increased, the electronic Dwell setting required to achieve the same valve opening time has also been reduced. The new valve assembly really is a Win, Win, Win, Win scenario.
Another first for the Eclipse Ego, the Ego9 utilizes Off-Set lower bores in order to solve a geometric conundrum that plagues the average stacked-tube marker. In previous Egos, and all other stacked tube markers, the upper (barrel and bolt) bore and lower (poppet valve and rammer) bores are separated by a fixed amount that is governed by a) the diameter of the barrel and threads and b) the diameter of the valve chamber. So what is the problem? Well, all the driving (accelerative and deccelerative) forces are tied to the centre-line, or axis, of the lower bore and specifically the rammer. However, there is a large mass, namely the bolt and pin, that is also tied to the rammer, but is in an orientation that is called “Off Axis”, meaning that the centre of mass of the bolt does not operate along the same axis as the rammer. When the rammer accelerates, the force acts on the bottom of the bolt pin, which in turn pushes the bolt forward. But because centre-line of the bolt is a distance from the centre-line of the rammer, it creates an Off-Axis load, which produces a twisting action on the bolt and pin. When the rammer comes to a stop, the same happens again. The rammer stops, but the bolt tries to carry on, but because it is connected to the rammer by the bottom of the pin, the bolt creates a twisting motion about the point the pin connects to the rammer. The result is that every time the bolt is accelerated or stopped (by hitting the valve or the rear bumped) the bolt tries to resist that action and creates a force that wants to tip the marker forward or backwards. These forces and actions are some of the contributing factors to what the user feels and interprets as Kick.
So what is different about the Ego9? To start with the valve chamber axis and the rammer chamber axis are no longer the same. By separating these 2 bores we have been able to move the rammer axis up in the body of the marker, closer to the bolt axis. By moving the 2 axis closer together, and joining the bolt and the rammer with a much shorter pin, the Off-Axis effect of the bolt on the rammer is greatly reduced. And as such, the feeling of kick bolt system is also reduced.
Not only that, but the constant drive of the Ego line to bring the grip-point, or heal of the hand up closer to the barrel axis has been further enhanced by moving the rammer axis up closer to the bolt and barrel. This raised grip position is a key element in giving every Ego that “point-ability” factor to the feel that players love about these markers
Larger Valve Chamber
For the last 4 years the Ego valve chamber has stayed roughly the same volume, and manipulation of the valve guide dimensions, solenoid valve and in-line regulator volume has allowed tweaking and refinement of the operating pressure of the gun. With the Ego9 a completely revised body layout has allowed the volume of the valve chamber to grow by approximately 30%. This larger valve chamber, combined with the higher rammer speeds afforded by the new solenoid assembly (see above) have meant that with the standard valve guide (same orifice dimensions as Ego7 and Ego8) the operating pressure has been dropped to an incredibly low 160psi at 290fps. This reduced operating pressure is well below any other previous Ego, and is in the kind of operating range that is normally associated with a Spool Valve type marker. The benefits of a reduced operating pressure? Quieter shot signature and reduced peak pressure behind the ball.
