I like the way the offsetting boss is handled, kinda like Kjells dog-leg boss (Bent shaft) !
What looks a little odd is in the animation, i see lateral piston movement produced from the arking swashplate...if you look closely you can see the piston moving out of concentricity of the said cylinder ! Karcha have similar patents on a system for a water blaster which they so kindly named swashdrive
I kinda wonder how useful all those patents are in todays world with all the copies / knockoffs that come out of china
