Title:
流体から粒子を分離するための装置およびブリードされた流体を本流に導入するための弁
Document Type and Number:
Japanese Patent JP4387461
Kind Code:
B2
Abstract:
A bleed valve (30) for introducing bled fluid to a mainstream fluid through apparatus (16) across which a pressure differential occurs, characterized in that the bleed valve (30) is adapted to open so as to bleed fluid into the mainstream fluid when the pressure differential across the apparatus (16) falls below a predetermined value. This arrangement is particularly appropriate to vacuum cleaners incorporating cyclonic dust-separating apparatus in that the bleed valve is more reliably operated in response to a reduction in airflow. This ensures efficient functioning of the cyclonic dust-separating apparatus and reduces the risk of overheating of the motor.
