Abstract

A suction-type swimming pool cleaner having an elongate body formed by a suction head and an elongate, tubular structure extending from the suction head, the orientation of the body being at least partially controlled by arms carrying a float and a connection bracket connecting the arms in a releasable manner to the body, to allow the float to be connected to the body at any selected one of a number of different positions along the body length, the head includes a valve chamber having a wedge-shaped hammer oscillating in the chamber responsive to suction flow through the head, the hammer seating against shoulders in the chamber, the shoulders being partially rebated and partially sloped to ensure that they are flushed clean of any particulate matter which could interfere with proper hammer seating.

Description

BACKGROUND TO THE INVENTION

[0001] THIS invention relates to a suction type pool cleaner.

[0002] Suction-type pool cleaners are well known and have been in widespread use for a number of years. Generally suction-type pool cleaners are connected by a flexible hose to a suction point, typically a suction inlet at the weir of a swimming pool. The cleaner operates on the submerged surface of the pool and water is sucked through it by the pump of the swimming pool filtration unit.

[0003] One particularly popular suction-type pool cleaner has a valve chamber with an inlet which in operation is situated near to the submerged surface and through which a water flow is sucked. The chamber accommodates a valve member or hammer which oscillates under the influence of the suction flow and which directs the flow alternately to one or the other of a pair of outlet passages leading away from the valve chamber to the hose. The resulting variations in momentum of the water flow as well as variations in the...
