Conceitualmente, arma de fogo nada mais é do que um artefato para propulsão de projéteis, por meio de expansão de gases originados na queima controlada de um propelente, mais especificamente a pólvora contida em uma câmara fechada, exceto pelo cano que conduz o projétil. Conceptually, a firearm is nothing more than an artifact for projectile propulsion, through the expansion of gases from the controlled burning of a propellant, more specifically the powder contained in a closed chamber, except for the barrel that carries the projectile.
Basicamente, uma arma de fogo é constituída pelo cano, câmara de expansão de gases, culatra, sistema de disparo, sistema de segurança, sistema de mira, cabo, carregador de munição. Nesse sentido, as armas podem ser fixas ou de assentamento e portáteis ou pessoais. Essas últimas podendo ser subdividida em curtas ou longas. Basically, a firearm consists of the barrel, gas expansion chamber, breech, firing system, security system, sighting system, cable, ammunition magazine. In this sense, weapons may be stationary or grounding and portable or personal. The latter can be subdivided into short or long.
Em uma forma geral, as armas curtas são as utilizadas na proteção individual podendo ser definidas como revolveres e pistolas, cada qual com suas vantagens e desvantagens. In general, short weapons are those used for personal protection and can be defined as revolvers and pistols, each with its own advantages and disadvantages.
Na pistola o disparo é decorrência do acionamento de sistemas de acionamentos simples, duplos e "safe action", por meio da percussão da espoleta pelo percussor e consequente aproveitamento da queima resultante dos gases através do ferrolho, ejetando o estojo da munição deflagrada e inserindo uma nova munição para a câmara de explosão. In the pistol the firing is a result of the activation of single, double and "safe action" systems, by percussion of the fuse by the percussor and consequent use of the resulting gas burning through the bolt, ejecting the triggered ammunition case and inserting a new ammo for the blast chamber.
Desse modo, o funcionamento de uma arma de fogo envolve a explosão de uma quantidade de gases que, por sua vez, resulta em forças com vetores em diversas direções, suficientes para deslocar a arma em prejuízo ao alvo. Thus, the operation of a firearm involves the explosion of a quantity of gases which, in turn, results in forces with vectors in several directions, sufficient to displace the weapon to the detriment of the target.
No caso de armamentos automáticos e semi-automáticos, como, por
exemplo, pistolas, em paralelo a explosão dos gases, ocorre o deslocamento do ferrolho (slide), que expulsa o projétil atirado e capta novo projétil. Nesse movimento do ferrolho, a força de inércia é totalmente transferida para a mão do atirador, que deve ser submetido a treinamento severo. In the case of automatic and semi-automatic armaments such as For example, pistols, in parallel with the explosion of gases, occur the displacement of the bolt (slide), which expels the thrown projectile and captures new projectile. In this bolt movement, the force of inertia is fully transferred to the shooter's hand, which must undergo severe training.
Sendo assim, toda a energia necessária, proveniente e remanescente do disparo, descarrega "instantaneamente" no batente da armação (frame) quando do final do curso do ferrolho à retaguarda, que decorre para uma série de inconvenientes, a saber: Thus, all necessary energy from the remainder of the shot discharges "instantly" to the frame stop at the end of the rear bolt stroke, which results in a number of drawbacks, namely:
Maior desgaste do equipamento; Greater wear of the equipment;
Menor vida útil; Shorter service life;
Compactação estrutural dos componentes que colidem, gerando tensões, vibrações e massas indesejáveis; Structural compaction of colliding components, generating undesirable stresses, vibrations and masses;
■J Imprecisão; ■ J Inaccuracy;
Desconforto para o atirador. Discomfort for the shooter.

O bloco de carne tem um flange frontal com superfícies flange que engatam superfícies de apoio correspondentes da estrutura, para distribuir forças e energia à estrutura durante recuo da arma de fogo. The prior art discloses some patent documents addressing the negative effects generated in the recoil of weapons in general, such as PI 0404608-0, which refers to a meat block assembly with a weapon block. meat and a guide rod employed in a firearm that has a structure constructed of synthetic polymeric material. The cam block has a front flange with flange surfaces that engage corresponding support surfaces of the frame to distribute forces and energy to the frame during firing back.
O PI 9302144-5 compreende elementos para moderar o coice das peças móveis de uma arma de fogo. PI 9302144-5 comprises elements for moderating recoil of moving parts of a firearm.
Já o PI 9500976-0 se refere a empunhadura deformável ergonómica a ser utilizada o em armas de fogo, fabricada em material elástico de forma a obter um contorno básico dito anterior. PI 9500976-0 refers to the ergonomically deformable handle to be used in firearms, made of elastic material to obtain a basic contour said above.
