摘要： AB A swimming pool cleaner comprising a car having two turbine-driven rear wheels and a steerable front wheel guided on an endless track in the form of a weighted tube resting on the bottom of the pool. Water under pressure from the pool circulation system is delivered to the turbine to drive the rear wheels, and exits through two elongated sweep hoses which direct the water in jets into the pool.

摘要： A swimming pool heater having a by-pass control including a spring-loaded by-pass valve formed by a hinged valve plate, and means for increasing and decreasing the spring force tending to close the by-pass valve in response to changes in the temperature of the flow out of the heater, thereby to avoid overheating as a result of an input pressure drop or an input temperature rise. The temperature-responsive means include a heat-expansible and contractible member connected to a base element for the spring, and two spring return units for assisting in relieving the spring force as the member contracts.
