Gas cylinder with two concentric bodies and an intermediate chamber, with a control rod (16) and gas passage valve (29) that withstands multidirectional drive action, enabling the drive action on an area that resembles a semi-sphere (18) and with the direction in which the executing force of the control action is applied proving immaterial, as it can be either on the rod (16) itself or on a device attached to its end with a blind hole or through hole. <IMAGE>
