Mechanical lever-driver for pressure pump

Abstract

Examples of a lever-driven pumping system are described. The lever-driven pumping system can comprise a motor that is configured to provide an input energy to drive a crank shaft, a positive displacement pump with at least one piston and a pump chamber arranged in a pump housing, and a lever driver with at least one lever that has a load end in communication to the crank shaft and a force end in communication with the at least one piston. A fulcrum point of the lever is formed at a predefined distance from the load end and the force end so that a distance from the fulcrum to the load end is greater than a distance from the fulcrum to the force end. A load connector is configured to connect the load end of the at least one lever to the crank shaft while a force connector is configured to connect the force end of the at least one lever to the piston rod. An output energy provided at the force end of the at least one lever and thus the output energy of the pumping system is amplified by the at least one lever and is greater than the input energy provided by the motor at the load end of the at least one lever.

1 . A lever-driven pumping system, the system comprising:
 a motor configured to provide in input energy to the pumping system;   a positive displacement pump comprising a housing with at least one piston and at least one chamber, the at least one piston being configured to reciprocally oscillate within the at least one chamber, each piston having a piston rod connected to a piston body and projecting away from the piston body; and   a lever driver, the lever driver comprising:
 at least one lever having a load end in communication to the motor, the input energy of the motor being applied to the load end of the at least one lever; a force end in communication with the piston rod; a body extending between the load end and the force end; and a fulcrum point formed at a predefined distance from the load end and the force end so that the at least one lever oscillates up and down on the fulcrum point, wherein a distance from the fulcrum to the load end is greater than a distance from the fulcrum to the force end; 
 a load connector to bring the load end of the at least one lever in communication with the motor such that the input energy generated by the motor is applied to the load end of the at least one lever; and 
 a force connector to connect the force end of the at least one lever to the piston rod such that an output energy provided by the at least one lever is applied to the piston, 
   wherein the output energy at the force end of the at least one lever is greater from the input energy applied at the load end of the at least one lever.   
     
     
         2 . The system of  claim 1 , wherein the lever driver comprises a pivot block, the at least one lever being pivotally connected to the pivot block at the fulcrum point. 
     
     
         3 . The system of  claim 1 , further comprising a crank having a crank shaft, the crank shaft being in communication with the motor, the motor rotating the crank shaft. 
     
     
         4 . The system of  claim 3 , wherein the crank further comprising at least one plate connected to the crank shaft, the at least one plate having a connector mounted eccentrically on the plate, the load connector of the at least one lever being connected to the crank plate at such eccentrically positioned connector. 
     
     
         5 . The system of  claim 4 , wherein the load connector comprises an elongated arm with a lobe end formed at one end of the elongated arm and a hinge on its opposite end, the lobe end being connected to the crank plate while the hinge being connected to the load end of the lever. 
     
     
         6 . The system of  claim 1 , wherein the lever driver is mounted in the pump housing. 
     
     
         7 . The system of  claim 3 , wherein the crank is mounted in the pump housing. 
     
     
         8 . The system of  claim 7 , wherein the lever driver is mounted in the pump housing. 
     
     
         9 . The system of  claim 3 , wherein the lever driver further comprises a housing to accommodate the lever driver and the crank, the housing being adjacent to the pump housing. 
     
     
         10 . The system of  claim 1 , wherein the motor is powered by a battery.
