Abstract
A fluid-fuel operated setting tool for driving in fastening elements includes a housing (11) with a combustion chamber provided therein for combusting fluid fuel, with a released energy of combustion of the fluid being used for driving in a fastening element, and a reservoir (20, 20′, 20″) for storing the fluid fuel and attached to the tool housing and having, in a direction parallel to its longitudinal axis (22), a jacket (21) shape and habit of which are defined by inscribed and circumscribing envelope circles (211, 212), with the cricumscribing envelope circle having a size of its circumference greater than the size of the circumference of the insribed envelope circle.

A fluid fuel-operated setting tool for driving in fastening elements, comprising a housing (11) with a combustion chamber provided therein for combusting fluid fuel, with a released energy of combustion of the fluid fuel being used for driving in a fastening element;
- a reservoir (20, 20′, 22″) for storing the fluid fuel and from which the fluid fuel is fed to the combustion chamber;
- and means (17, 27) for attaching the fuel reservoir (20, 20′, 22″) to the housing (20),
- wherein the fuel reservoir (20, 20′, 22″) has, in a direction parallel to a longitudinal axis (22) thereof, a jacket (21) having an envelope shape and habit of which are defined by inscribed and circumscribing envelope circles (211, 212);
- wherein the fuel reservoir (20, 20′, 20″) is formed so that in a direction perpendicular to the longitudinal axis (22) of the fuel reservoir (20, 20′, 20″), the jacket envelope-defining, inscribed and circumscribing envelope circles (211, 212) stay in relationship such that a size of a circumference of the circumscribing envelope circle is greater than a size of a circumference of the inscribed envelope, and
- wherein the jacket (21) of the fuel reservoir (20, 20′, 20″) is formed of a jacket sections (23, 24) having different radii.
A fluid fuel-operated setting tool for driving in fastening elements, comprising a housing (11) with a combustion chamber provided therein for combusting fluid fuel, with released energy of combustion of the fluid fuel being used for driving in a fastening element;
