Abstract

Official abstract text for this publication.

The invention relates to a swimming-pool cleaning apparatus which comprises: a body; at least one hydraulic circuit for circulating liquid between at least one liquid intake and at least one liquid outlet, and through a filtering device of the cleaning apparatus; a fluid-circulation pump installed in the hydraulic circuit downstream from the filtering device; means for adjusting the pressure inside the hydraulic circuit upstream from the circulation pump, in response to a detected variation of said pressure, said pressure-adjustment means comprising: at least one secondary liquid intake (21) connected to the hydraulic circuit, upstream from the circulation pump, said at least one secondary liquid intake (21) being provided with a valve (22) mounted rotatably movable about an axis of rotation, and with means for driving the valve from an open position to a closed position, said means for driving the valve comprising a float (26), the orientation and/or the force of which depend on the orientation of the cleaning apparatus relative to a horizontal plane.

First claim

Opening claim text (preview).

1 - 7 . (canceled) 8 . Swimming pool cleaning apparatus comprising: a. a body comprising a liquid inlet and a liquid outlet; b. a filtration device; c. a hydraulic circuit for circulating liquid between the liquid inlet and the liquid outlet and through the filtration device; d. a fluid circulation pump installed in the hydraulic circuit downstream of the filtration device; and e. means for adjusting the pressure in the hydraulic circuit upstream of the fluid circulation pump in response to a detected variation of this pressure, said means comprising a secondary liquid inlet connected to the hydraulic circuit upstream of the fluid circulation pump, said secondary liquid inlet being equipped with a valve configured to move from an opened position to a closed position as a function of an orientation of the body relative to a horizontal plane.
