Abstract

a presente invenção se refere a um cilindro extensível (10), em particular, para uma cabeça de perfuração (2000), a uma cabeça de perfuração compreendendo um cilindro extensível, e a um método de operação de uma cabeça de perfuração. em concordância com a presente invenção, o cilindro extensível compreende um eixo (100) com um volume de anel de eixo (101) entre uma parte interna (110) e uma parte externa (120) do eixo (100); um pistão (200) com um volume de anel de pistão (201) entre uma parte interna (210) e uma parte externa (220) do pistão (200); o pistão (200) sendo movível com respeito para o eixo (100) ao longo de um eixo geométrico longitudinal (lx); uma extremidade proximal (221) da parte externa (220) do pistão (200) sendo disposta entre a parte interna (110) e a parte externa (120) do eixo (100); e uma extremidade distal (111) da parte interna (110) do eixo (100) sendo disposta entre a parte interna (210) e a parte externa (220) do pistão (200); e em que o cilindro extensível (10) é extensível e/ou retrátil ao longo do eixo geométrico longitudinal (lx).The present invention relates to an extendable cylinder (10), in particular to a drill head (2000), a drill head comprising an extendable cylinder, and a method of operating a drill head. In accordance with the present invention, the extensible cylinder comprises an axle (100) with an axle ring volume (101) between an inner portion (110) and an outer portion (120) of the shaft (100); a piston (200) with a piston ring volume (201) between an inner portion (210) and an outer portion (220) of the piston (200); the piston (200) being movable with respect to the axis (100) along a longitudinal geometrical axis (1x); a proximal end (221) of the outside (220) of the piston (200) being disposed between the inside (110) and the outside (120) of the shaft (100); and a distal end (111) of the inner portion (110) of the shaft (100) being disposed between the inner portion (210) and the outer portion (220) of the piston (200); and wherein the extensible cylinder (10) is extensible and / or retractable along the longitudinal geometrical axis (1x).
