Adrianmsmith Sorry, no, I did just mean turn on earlier after pulling the lever or flushing.
It really isn’t an issue there’s a maybe 1 second lag. just curious.
It’s a mechanical issue related to the group design of all the clone groups of LSM from ALL manufacturers of said groups. It was originally done for a very good reason, allowing the piston seal to pass inlet ports that used to be much higher in the chamber before water entered. minimising washout of lubes and pretty much eliminate the chance of water passing the O’ring at the top of the piston (unless the piston pressure seal was worn out).
Interestingly a change done perhaps 8 years ago by many of the group manufacturers to lower the inlet ports to below the resting position of the piston. This prevented the piston seal from ever passing the port and the inevitable edge nibbling that happens when it comes back down expanded under pressure. This gave an opportunity which every single one of them missed (3 opportunities in fact) to address something which could have made a dramatic difference and given KVDW variable max pressure capability similar to their super expensive and complex lever groups. I spotted this opportunity around 6 months ago.
- The ability to vary the max pressure of a shot withing a range 8.8 to 11.5 bar (if you have the safety system) and a smaller range if you don’t
- The ability to increase the swept volume by probably 30%
- The ability to introduce a lever assistance mode (where the lever can be made much easier to pull through the initial difficult 40% of it’s motion for those with arthritis or shoulder problems
The flush lever was the beginning of testing a system that already exists purely to flush the group on top end KVDW machines (their is electronic). I felt a mechanical system would be better, simpler and less prone to error. Later it will move to a variable piece on the lever mechanism, which can be moved to change the timing of the water valve opening and increase or reduce the pressure in the group (and have the same effect on swept volume, because of a reduction of air).
Plus an addition of a flush lever handle both sides.
- for left or right handed people
- for lever assistance mode
