Abstract
A manually operated tool such as a parting-off grinder, chainsaw or similar device has a tank housing which contains a fuel tank. The tool has an air cleaning unit, the tank housing being connected to the clean air side of the air cleaning unit via a bleed device. A simple design in which leaks are avoided results if a reservoir wall of the tank housing and a housing wall of the air cleaning unit are positioned adjacent to one another and the bleed device comprises a bleed opening which passes through the reservoir wall and the housing wall.
Claims21
A manually operated implement comprising:
- an air cleaning unit;
- and
- a tank housing, wherein a fuel tank is formed in the tank housing, wherein a reservoir wall of said tank housing and a housing wall of said air cleaning unit are disposed adjacent to one another, wherein said tank housing is in communication with a clean air side of said air cleaning unit via a bleed device, wherein the bleed device includes a bleed opening, wherein the bleed opening is disposed in said housing wall of said air cleaning unit, wherein the bleed opening is a continuous bleed opening that runs through the reservoir wall of the tank housing and the housing wall of the air cleaning unit.
A manually operated implement comprising:
- an air cleaning unit;
- and
- a tank housing, wherein a reservoir wall of said tank housing and a housing wall of said air cleaning unit are disposed adjacent to one another, and wherein said tank housing is in communication with a clean air side of said air cleaning unit via a bleed device that includes a bleed opening which extends through said reservoir wall and said housing wall, wherein said reservoir wall of said tank housing is formed on said housing wall of said air cleaning unit.
A manually operated implement comprising:
- an air cleaning unit;
- and
- a tank housing, wherein a reservoir wall of said tank housing and a housing wall of said air cleaning unit are disposed adjacent to one another, and wherein said tank housing is in communication with a clean air side of said air cleaning unit via a bleed device that includes a bleed opening which extends through said reservoir wall and said housing wall, wherein said tank housing is formed of two partial shells, a plane of separation of which extends transverse to a longitudinal direction of said implement.
A manually operated implement comprising:
- an air cleaning unit;
- and
- a tank housing, wherein a reservoir wall of said tank housing and a housing wall of said air cleaning unit are disposed adjacent to one another, and wherein said tank housing is in communication with a clean air side of said air cleaning unit via a bleed device that includes a bleed opening which extends through said reservoir wall and said housing wall, wherein said air cleaning unit includes a cyclone unit that is at least partially monolithically formed with said tank housing.
