Hydraulic control

Abstract

A hydraulic directional control is disclosed. The hydraulic directional control proposed herein provides, besides the already existing items, one pilot pressure sequence valve, one pressure vent valve with gauged vent for flux control, and one externally piloted stop valve.

1 . A hydraulic control comprising: 
 a pilot pressure sequence valve;    a pressure vent valve with gauged vent for flux control; and    an externally piloted stop valve.    
   
   
       2 . A hydraulic control as per  claim 1 , wherein the external and/or internal use of the pilot operated pressure control valve and the pressure vent valve with gauged vent for flux control that increase the load.  
   
   
       3 . A hydraulic control as per claims  1 , wherein the valves control of induced hydraulic pressure in the telescopic cylinder.  
   
   
       4 . A hydraulic control as per  claim 1 , wherein the external and/or internal use of the pilot operated pressure control valve liberate the recoiling of the telescopic cylinder stages.  
   
   
       5 . A hydraulic control as per  claim 4 , wherein the external and/or internal use of the pilot operated pressure control valve when liberating the recoiling of the telescopic cylinder, that increase the volume in the container.  
   
   
       6 . A hydraulic control as per  claim 1 , wherein pressure vent valve with gauged vent, that keeps the hydraulic pressure controlled and variable in function of the area of the telescopic cylinder stages.  
   
   
       7 . A hydraulic control as per  claim 1 , wherein the valves that keep compacting forces constant regardless the areas of the telescopic cylinder stages.  
   
   
       8 . A hydraulic control characterized by residues that are homogenously compacted throughout the entire container and the compacting force that is set to keep and assure that the compacted residue load is compatible with the equipment/vehicle and consequently with transportation road being used.  
   
   
       9 . A hydraulic control as per  claim 1 , wherein the pilot stop valve, that promotes the so-called “anti-pacifier” effect.  
   
   
       10 . A hydraulic control as per  claim 9 , wherein the pilot stop valve, that only allows the passage of hydraulic oil into the telescopic cylinder and consequently the open of that telescopic cylinder through the ejecting system, outward the container, if the compactor cover assembly is open.
