Abstract
A power tool comprises a housing and an inner mechanism mounted at least partially within the housing. The inner mechanism is configured to be reciprocally moveable with respect to the housing and the inner mechanism has a motor fan assembly. The power tool comprises an air inlet and an air outlet positioned in the housing and a cooling airflow path extending between the air inlet and the air outlet via the motor fan assembly. The power tool also comprises at least one air conduit located on the airflow path configured to guide the cooling airflow from the air inlet to the motor fan assembly wherein a first end of the air conduit is fixed and a second end of the at least one air conduit is a free end.
Claims18
A power tool comprising:
- a housing;
- an inner mechanism mounted at least partially within the housing and configured to be reciprocally moveable with respect to the housing, the inner mechanism having a motor fan assembly;
- an air inlet and an air outlet positioned in the housing and a cooling airflow path extending between the air inlet and the air outlet via the motor fan assembly;
- and
- at least one air conduit located on the airflow path configured to guide the cooling airflow from the air inlet to the motor fan assembly, wherein a first end of the air conduit is fixed and a second end of the at least one air conduit is a free end that is not directly fixed to other elements in the power tool.
A power tool comprising:
- a housing;
- an inner mechanism mounted at least partially within the housing and configured to be reciprocally moveable with respect to the housing, the inner mechanism having a motor fan assembly;
