    摘要： A grid unit for supporting a filter element used in a liquid filter comprises vertical supporting struts crossed by horizontal ribs positioned to cause the liquid to flow in a serpentine manner. A narrow slot at an end of the grid structure controls the flow of the liquid between the grid and a collecting trough. Rectangular construction of the grid unit facilitates joining a plurality of units to enlarge the area of the grid.

    摘要： A vortex-producing chamber has an inlet from the surface of a pool and an outlet at the bottom of the vortex chamber. A vortex is formed at this outlet which carries the water with any floating debris and the like with it into a tank from which it can be drawn out by action of a suction pump. In the usual arrangement, means such as a float is located in an upper portion of the tank at the water surface. If the tank water level drops abnormally low the float means comes down with the water and engages a seat dividing the upper and lower tank portions from each other and sealing the lower tank portion from air in the upper portion. A bypass conduit leading from a water source such as the pool itself supplies water to the lower tank portion to supply the pump demand when the lower portion is thus sealed from the upper portion.

    摘要： A skim tank for skimming surface water of a pool has an inlet from the surface of the pool to an upper part of the tank. A rotatable plate extending across the tank at a level below the inlet separates the upper tank portion from a chamber below the plate, and an opening through the plate permits the pool water from the inlet and upper tank portion to flow down to the chamber when the opening is not closed by a stopper, from where it is withdrawn through a conduit by a suction pump for filtering. A bypass conduit connects to the chamber from the pool such that when the stopper closes the opening, water is drawn into the chamber through the bypass line to supply the pump. The pool may be vacuum cleaned through a vacuum line connected at the opening of the plate and in order to close the bypass line during the vacuum operation, the rotatable plate is provided with a closure gate depending from it which blocks the inflow from the bypass to the chamber when the plate is rotated to the blocking position.
