A PUMP FOR USE IN A VACUUM CLEANER
A pump is for generating a suction for application to a vacuum cleaner dirty air inlet. There is a motor inside a motor outer casing and a fan outside the motor outer casing having a main inlet and a main outlet. The fan generates a main suction flow between the main inlet and the main outlet and cr...

| description | A pump is for generating a suction for application to a vacuum cleaner dirty air inlet. There is a motor inside a motor outer casing and a fan outside the motor outer casing having a main inlet and a main outlet. The fan generates a main suction flow between the main inlet and the main outlet and creates a region of under pressure. This under pressure is used to drive a secondary flow between a cooling air inlet to the motor outer casing and a cooling air outlet from the motor outer casing. The secondary air flow is induced by making use of an under pressure generated by the fan. |
