Abstract
A by-pass valve is affixed to the housing of a self-propelled submersible swimming pool cleaner. The pool cleaner includes a head having a suction chamber in which a propulsion mechanism is located for operation by water flow into the suction chamber. The head incorporates a by-pass inlet to the suction chamber downstream from the propulsion mechanism. A leaf spring biases the closure member over the by-pass inlet. The tension of the spring is overcome by the suction in the suction chamber when water flow into the chamber is blocked. Water flow is thus allowed into the suction chamber via the by-pass inlet. By placing the spring controlled by-pass inlet into the system flow stream between the cleaner propulsion mechanism and the system weir in the typical pool system, there is a small probability of the by-pass becoming blocked.
