Bleed air valve of a surface cleaning apparatus
First Claim
1. A surface cleaning apparatus comprising:
- (a) an air flow passage extending from a dirty air inlet to a clean air outlet;
(b) a cyclone comprising a cyclone air outlet and positioned in the air flow passage downstream of the dirty air inlet;
(c) a suction motor provided in the air flow passage downstream of the cyclone;
(d) a pre-motor filter upstream of the suction motor and downstream of the cyclone, the pre-motor filter having an upstream side and a downstream side; and
,(e) a bleed valve having an air inlet, an airflow passageway having a longitudinal axis and an air outlet, the air outlet positioned between the suction motor and the downstream side of the pre-motor filter and the longitudinal axis intersecting the downstream side of the pre-motor filter.

Abstract
A surface cleaning apparatus comprises an air flow passage extending from a dirty air inlet to a clean air outlet. The surface cleaning apparatus further comprises a cyclone comprising a cyclone air outlet and positioned in the air flow passage downstream of the dirty air inlet. A suction motor is provided in the air flow passage downstream of the cyclone. A pre-motor filter is upstream of the suction motor and downstream of the cyclone. The pre-motor filter has an upstream side and a downstream side. The surface cleaning apparatus further comprises a bleed valve having an air inlet and an air outlet. The air outlet is positioned between the suction motor and the downstream side of the pre-motor filter and facing the downstream side of the pre-motor filter.
