Abstract
A toy spa (10) is provided with water (56) and an aerating manifold (18) in the base (16) of the spa. Pressurized air is provided to the manifold via a bellows pump and passes through the water from openings (20) in the manifold. To reduce the surge effect of the bellows pump an expandable reservoir means (40) is provided between the bellows pump and the aerating manifold (18). Air is pumped from the bellows pump directly into the expandable reservoir through a one way valve (32) moved by the pressurized air. Air exits from the expanded reservoir via a restricted opening (44) which enables the pressurized air to be first stored within the expandable reservoir and to then be delivered to the manifold in a continuous, even manner.
