Embodiment Construction

[0053] figure 1 The prior swimming pool cleaner 10 shown in has a hollow body member 12 with a hollow 14 forming a fluid inlet port 16 at its seat 17 and a fluid outlet port 18 at its top 19 . Due to the reduced wall thickness, the top 19 has a slightly smaller outer circumference. A top cover 20 is secured at the top around the fluid outlet port 18 . The top cover 20 has a connection opening 22 to which a rotary tube 24 is connected via a wear ring 26 inserted in the opening 22 . A hand nut 28 is used to maintain the swivel tube 24 in place. The support 17 ends at about 45° at its trailing end and has an outwardly extending flange 30 to which a flexible disc (not shown) is attached.

[0054] The main body 12 is shown having been sectioned along its longitudinal center axis for access to components in the hollow. This member comprises a wedge shaped hammer valve member 32 pivotally connected to a divider 34 which is secured by a T-shaped fixing element 36 . Upstream to th...

Abstract

A self propelled pool cleaner is of compact narrow construction and comprises a diaphragm for propulsion, the present invention also provides a kit of parts for retrofitting a pool cleaner of the hammer type, the pool cleaner (10) having a hollow body (12) formed with a fluid inlet end (16) and a fluid outlet end (18) opposite to said inlet end, a divider (34) forming two separate flow passages in said hollow (14), and a hammer valve member (32) arranged to pivotally reciprocate about a pivot point to cause fluid to flow alternately in the flow passages. The kit has a tubular diaphragm member (50) for replacing the hammer valve member, an inner tube member (54) for replacing the divider and one end of which being adapted for connection to the diaphragm member, a diaphragm holder (52) adapted for fixing in said hollow adjacent to said inlet end to hold the diaphragm member in position in said hollow, a tube holder (56) adapted for fixing in said hollow adjacent to said outlet end to hold said tube in position in said hollow. A process for retrofitting the pool cleaner is also disclosed.

Description

technical field [0001] The present invention relates to a self propelled pool cleaner, and more particularly to a novel and efficient combination of compact pool cleaner units, to an improved pool cleaner and to improved pool cleaners Parts kit (kit). Background technique [0002] Submersible pool cleaners generally known in the prior art are illustrated by way of example with reference to US Pat. Prepare for clean surface contact. In general, pool cleaners are of two types, the first type comprising a valve in the form of a rocking hammer, while the second type uses a diaphragm. US Patent No. 4,351,077 is a schematic illustration of a hammer or flapper type valve. [0003] This configuration of the valve causes an intermittent shutoff of fluid flow through the tip as the valve oscillates between its open and closed positions, while this in turn causes a discontinuity phenomenon which results in a flow from the tip to the outlet from the swimming pool to its filter unit ...
