Fluid distribution system for pre-charged pneumatic (pcp) carbines or pistols

Fluid distribution system for PCP-propelled carbines or pistols with a firing mechanism (20) comprising a trigger (22) and a main valve (23), which is connected to a barrel (21);

• and
• a first reservoir (1) wherein the fluid to be distributed to the main valve (23) is provided at a pre-determined pressure, said first reservoir (1) being arranged inside a tubular element (3),
• a second reservoir (2), arranged inside the tubular element (3) and having the same pressure as the first reservoir (1);
• and
• a spacing element (4), which operates as a moving piston, arranged inside the tubular element (3), which separates the first reservoir (1) from the second reservoir (2),
• characterized in that
• the spacing element (4) is a valve,
• the tubular element (3) comprises a stop limit (14) for limiting the advance of the spacing element (4) in the direction of the second reservoir (2), and further,
• the tubular element (3) that at least partially surrounds the first reservoir (1), the spacing element (4) and the second reservoir (2), which, in an active position after the shot is fired, when the fluid pressure of the first reservoir (1) drops, the fluid of the second reservoir (2) pushes the spacing element (4) in the direction of the first reservoir (1) until the fluid pressure of the first reservoir (1) and the fluid pressure of the second reservoir (2) are balanced;
• and
• which, when in a loading position, once the fluid has been supplied to the first reservoir at a pre-determined pressure (1), said fluid of the first reservoir (1) pushes the spacing element (4) in the direction of the second reservoir (2) until the fluid pressures of the first reservoir (1) and of the second reservoir (2) are compensated;
• and further
• the volume of the first reservoir (1) is equal to the volume of the barrel (21).
