End stop control valve video. Can't find much on these dampers yet. Looks like a bottom out hydraulic cone and spring?
Anyone else have any thoughts. Someone said the ESCV was active but I'm not seeing it.
Update: ESCV explained with crappy "diagrams".
Shock absorbers function through the "resistance" of the fluid contained inside their body to flow through small restrictions in the piston. As you go over a bump, the rod of the shock absorber is pushed through the fluid inside. It is slowed down because the piston is a restriction to this movement of the shaft. This is the basic principle of a shock. If the shock is becoming shorter it is under "compression". If the shock is getting longer it is under "rebound". The piston of the shock has shims that flex and provide resistance to fluid flow through the pistons orifices.
The ESCV shocks on the bronco have three main features that separate them from a "traditional" run of the mill shock on everyday vehicles.....
1. External Reservoirs
2. Compression ESCV
3. Rebound ESCV
The external reservoir attached to the main shock body provides a few functions.
1. It contains the IFP or internal floating piston. This device separates nitrogen and shock fluid from mixing.
2. This nitrogen charge helps the shocks work better. It prevents cavitation, but we aren't going there right now.
3. The floating piston displaces when the rod takes up volume inside the shock body.
4. The reservoir allows extra fluid volume so the shock runs cooler.
Compression End Stop Control Valve:
This makes the shock have more resistance to movement under compression, toward the end of travel. The circular spring loaded device puts pressure on the compression shims as the shock gets closer to bottom. This adds resistance to movement. Think I hit a really big bump.... But it didn't smack hard on landing. It had extra resistance for big hits.
Rebound End Stop Control Valve:This makes the shock have more resistance to movement under rebound, toward the end of travel. The circular spring loaded device puts pressure on the rebound shims as the shock gets closer to bottom. This adds resistance to movement. Think I hit a really big jump.... But it didn't clang hard on takeoff when I left the ground....
