Document Type and Number:
Japanese Patent JPH0452600
Kind Code:
U
Abstract:
A heat-driven pump, a fluid suction porting (6) which admits liquid into a heating chamber (3) where it is heated to form bubbles within the chamber. The bubbles force fluid out of the chamber through condensation means (5) and can enter the condensation means where they condense to allow further fluid to be drawn into the pump. The bubbles are prevented from flowing through the suction porting due to capillary action in that porting. This porting includes means (12) for defining fluid passages which allow fluid to pass through into the heating chamber but prevent the bubbles from passing through due to capillary action and placing means (13) for detachably placing the fluid passage defining means in position.
