BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to air pumps producing high pressure and providing efficient and ergonomic use in the ground conditions. 
     2. Background Art 
     Nowadays, there are pumps which produce high pressure for filling guns and aqualungs. The working process of these pumps is as follows: chambers in the air pump are conjoined from bigger to smaller; air into the air pump is guided to the biggest chambers through to the smallest chamber and fills the tubes with high pressure air. 
     For example, U.S. Pat. No. 5,885,061; discloses a pump in which the air moves from the pump body into the pump; guided to the chambers in order from bigger chambers to the smaller chamber and fills in to the tubes. 
     Also U.S. Pat. No. 6,702,556; discloses that the air into the air pump is guided through the chambers by air valves and o-rings and fills into the tubes. 
     However, in the above-mentioned patent specifications; there are no disclosed barometers or other gauges which measure the pressure of the air when guided through the bigger chamber to the smaller chamber filling into the tubes; also there are no filters disclosed to filter the air from dust and such materials before the air gets into the pump. 
     To address these issues, some technical improvements have been made; one of those improvements is disclosed in English Patent Specification number GB 2398354, in which the air into the pump is first filtered by an air filter and guided through the bigger chamber to the smaller chamber by the air valves and o-rings and fills into the tubes as intended. Also, there is a barometer which measures pressure in the pump. 
     The present disclosure further provides that within the air pump producing high pressure; it is disclosed that the air pump producing high pressure includes a reservoir, cavity, or compartment to store parts, make the pump pillar more ergonomic for the user, and provide fast and easy set up. 
     BRIEF SUMMARY OF THE INVENTION 
     The object of this invention is to produce a high pressure air filter that contains a reservoir in the pump handle which provides more comfortable and ergonomic usage and also provides more efficient usage because the air filter is built into the pump handle. 
     Another object of this invention is to produce an easily disconnected/connected air pump producing high pressure for users in ground conditions. 
     Another object of the invention is to provide an air pump producing high pressure wherein the pump pillar provides ergonomic configuration for users.

     DETAILED DESCRIPTION OF THE INVENTION 
     The above-mentioned air pump producing high pressure ( 1 ) contains a pump handle ( 2 ), a body ( 30 ) and a mooring pin ( 25 ). Pump handle ( 2 ) includes an air inlet slot ( 3 ). Pulling the pump handle upwards allows air through the air inlet slot ( 3 ) and into the body ( 30 ). Air enters the body ( 30 ) through a first chamber ( 6 ) which fills with air through the air inlet slot ( 3 ); also located between the movable external pipe ( 4 ) and the piston rod ( 5 ); air inlet valve ( 7 ) which is closed by the internal pressure when the pump handle ( 2 ) is pushed; the second chamber ( 9 ); in which the air in the first chamber ( 6 ) enters through open, air direction valves ( 11 ); also located between the movable external pipe ( 4 ) and the second standpipe ( 8 ); the third chamber ( 10 ) located between the first stand pipe ( 13 ) and the piston rod ( 5 ); the smallest volume fourth chamber ( 15 ); located at the far end of the first stand pipe ( 13 ); (which is the last place where the air in second chamber and the third chamber passes through last before the tube when the direction valves closed because the pressure occurs when the pump handle is pulled upwards again and valve with the movable o-ring on the piston rod opened); and the piston ( 14 ); the pump handle ( 2 ); which has a dust and moisture filter; a reservoir; and guides the air in the fourth chamber to get through the tube by closing the o-ring ( 12 ) valve to avoid the air passes through the second and third chamber when pushed again. 
     Air direction valve ( 11 ) contains a channel which has rounded elements to guide the air passing through the chambers and at least an o-ring separating the chambers. 
     Pump handle ( 2 ) separated into two part by the pump connector ( 16 ) which mounted in the middle of the handle; also contains the reservoir ( 20 ) which is placed under the cover ( 17 ) on the first section ( 18 ) of the handle and an air filter ( 21 ) which filters the dust and the damp of the air which get into the second section ( 19 ). 
     User can put the maintenance and repair kit and spare parts or other items into the reservoir and carry the items in a safe condition. 
     Air filter ( 21 ) of the invention related air pump producing high pressure ( 1 ); contains the first filter cartridge ( 22 ) which filters the dust in air and the second filter cartridge ( 23 ) which filters air moisture. 
     The first filter cartridge ( 22 ) and the second filter cartridge ( 23 ) can be easily removed periodically and easily replaced with the new ones by the user. 
     The pump handle ( 2 ) of the air pump producing high pressure ( 1 ) can be removed from the pump body ( 30 ) by rotating. The mooring pin ( 25 ) can be removed from body ( 30 ) by pulling the dowel ( 24 ). Thus, the pump ( 1 ) can be easily assembled and disassembled. In one embodiment, the air pump producing high pressure ( 1 ) contains an adjustment screw ( 26 ) which is mounted between the mooring pin ( 25 ) and the body ( 30 ). The adjustment screw ( 26 ) can be used to adjust the pump according to the user&#39;s joint movements so the user can move and use the pump ( 1 ) more easily. 
     The pressure gauge ( 27 ) of the invention related air pump producing high pressure ( 1 ); is embedded into the body ( 30 ) to avoid external damages for example if the pump ( 1 ) is dropped.
