Abstract
The invention relates to an operating substance tank (1), especially for a portable handheld work apparatus (2) having a fill opening (3) and an outflow opening (4). The operating substance tank (1) is configured from a first housing part (6) and a second housing part (7) connected to the first housing part in order to configure the operating substance tank (1) in a simple assembly so that the operating substance can be made available without disruption. A filter wall (8) is configured as one piece from a housing part (6) and partitions the tank housing (5) of the operating substance tank (1) into at least two spaces (9, 10).

An operating substance tank for a portable handheld work apparatus, the operating substance tank comprising:
- a tank housing having a tank interior and including a first housing part;
- and, a second housing part connected to said first housing part and defining said tank interior conjointly therewith;
- a filter wall for trapping contaminants contained in said operating substance and said filter wall being configured as one piece with said first housing part;
- said filter wall extending over the interior cross section of said tank so as to partition said tank housing into at least first and second spaces;
- said first housing part including a fill opening formed therein for filling said operating substance into said first space;
- said tank including an outflow connection through which said operating substance is drawn from said second space;
- and,
- said outflow connection being disposed in said second space downstream of said filter wall so that said contaminants are prevented by said filter wall from clogging said outflow connection as said operating substance is drawn by said work apparatus during operational use thereof.
A work apparatus comprising:
- an apparatus housing;
- a tank for holding an operating substance and said tank including a tank housing;
- said tank housing having a tank interior and including a first housing part;
- and, a second housing part connected to said first housing part and defining said tank interior conjointly therewith;
- a filter wall for trapping contaminants contained in said operating substance and said filter wall being configured as one piece with said first housing parts part;
- said filter wall extending over the interior cross section of said tank so as to partition said tank housing into at least first and second spaces;
- said first housing part including a fill opening formed therein for filling said operating substance into said first space;
- said tank including an outflow connection through which said operating substance is drawn from said second space;
- said outflow connection being disposed in said second space downstream of said filter wall so that said contaminants are prevented by said filter wall from clogging said outflow connection;
- and,
- said second housing part being defined by said apparatus housing.
