The invention relates to innovation and material improvement over a distributor of the Art used for hoists in conjunction with a plurality of attachments. In particular the invention results in improved hitch regulation percentage, improved flow modulation and lower response time. These innovations cumulatively result in material technical and economic efficiency compared to the variant known to the Art.
DESCRIPTION OF PRIOR ART
Reference is invited to the following existing patent and an application for patent made by the very applicant which is the applicant in the present application:
Patent No. 197333 effective date 16 November 1998 issues by the Patent Office, Government of India.
Patent Application No. 201911026560 dated 3 July 2019 titled A REINVENTED DISTRIBUTOR FOR HYDRAULIC HOIST
The aforesaid patent application discloses an invention related to a Distributor [Control Valve] that marks substantial innovation and improvement over the Art as envisaged in the disclosed Patent above.
The present application discloses a Control Valve that marks substantial improvement over the Control Valve of the Art. The innovations disclosed in the present application materially and innovatively improve three critical aspects of the Control Valve of the Art: improved hitch regulation percentage, improved flow modulation and lower response time

SUMMARY OF THE PRESENT INVENTION
In a typical embodiment of the Art the improved distributor being such the operation leads to generation of quick setting of implements, better field performance in order to minimize wheel slippage and better fuel economy. Control Valve quick reacts to changes in the loading in either the Top or Lower Link which are due to changes in the Draft or Pull required by the implement; the innovative line contact feature of piston to sleeve results in substantially improved hitch regulation and fast response in lowering speed. The innovations lead to improve the Hitch regulation percentage from prior 34% (of the Art) to improved 25%. This is a marked improvement that can be empirically assessed. The hydraulic medium is secured on the basis of an innovative metal to metal line contact for blocking the leakage. Generation of leakage leads to the internal dropping of the oil causing marked inefficiency, heating load, inter-mitten stoppages. In addition, the spool diameter has been increased to 10 mm, from the existing 6 mm in the Art. This leads to a marked improvement in flow modulation, by allowing higher ojl flow to the cylinder for fast lifting and same initial first jump for smooth working without deterioration of host device efficiency. This also leads to quick Jjfting and fast lowering which are substantial improvements over the disclosed Art.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF DISCLOSED INVENTION
In a typical embodiment of the Art the improved distributor being such the operation leads to generation of quick setting of implements, better field performance in order to minimize wheel slippage and better fuel economy. Control Valve quick reacts to changes in the loading in either the Top or Lower Link which are due to changes in the Draft or Pull required by the implement; the innovative line contact feature of piston to sleeve results in substantially improved hitch regulation and fast response in lowering speed. The innovations lead to improve the Hitch regulation percentage from prior 34% (of the Art) to improved 25%. This is a marked improvement that has been empirically assessed. The hydraulic medium is secured on the basis of an innovative metal to metal line contact for blocking the leakage. Generation of leakage leads to the internal dropping of the oil causing marked inefficiency, heating load, inter-mitten stoppages. In addition, the spool diameter has been increased to 10 mm, from the existing 6 mm in the Art. This leads to a marked improvement in flow modulation, by allowing higher oil flow to the cylinder for fast lifting and same initial first jump for smooth working without deterioration of host device efficiency. This also leads to quick lifting and fast lowering which are substantial improvements over the disclosed Art. FIGURE-4 depicts the innovative design of the piston/ sleeve interface leading to marked improvement in the Hitch Regulation. FIGURE-1 graphically depicts this improvement.
The spool diameter in the present invention is incased from 6 mm in the Art to 10 mm. This leads to better flow modulation compare to diameter 6 mm spool; the device in its preferred embodiment facilitates higher oil flow to cylinder for fast lifting and the same initial first jump for smooth working without deterioration of Tractor efficiency. FIGURES 2 and 3 depict these improvements graphically.
The improved Hitch Regulatio combined with improved flow modulation reduces the lift and lowering time for movement of the arm of the host. This leads to material efficiencies.
The process being such the operation leads to maintain depth of approx. 12-15 inches in cultivator without deterioration of Tractor efficiency.
The process being such the operation leads to maintain minimum depth of Seed Drill to approx. 1-5 to 4.0 inches in order to proper seeding and without deterioration of Tractor efficiency.
The process being such the operation leads to maihtain smooth levelling in the soft F Jon^?'^01^*'^ ^ffti^ deterioration of Tractor efficiency.
