Abstract: An improved sprinkler has a flow altering device to change water direction and control the direction of a blade wheel. A gear set causes a sprinkler head's repetitive rotation. The sprinkler head includes a set of corresponding upper plate and lower plate to divide an interior chamber of the sprinkler head to two chambers: a control chamber and a gear chamber. A water inlet pipe connects only with the control chamber to provide water to enter the control chamber. The upper plate and the lower plate form a filtering channel interconnecting between the control chamber and the gear chamber. The water from the control chamber can flow into the gear chamber through the filtering channel. The filtering channel filters the large/coarser particle debris in the water and the water flowing into the gear chamber can lubricate and cool the gear set in the gear chamber.

Abstract: An easy-type water pressure reducing apparatus comprises a connecting tube having a bore extending through an inlet end and an outlet end. The bore has an annular seat with a smaller-diameter inlet chamber integrally extending at both sides to which a movable element with an inlet port to receive a spring element is mounted. The movable element also includes positioning guide blocks to fit to water-guiding vents of the inlet chamber, and a ringed groove with a sealing ring to abut tight against the inlet chamber, forming a back-and-forth movable positioning space there-between. Therefore, when water pressure at the outlet end is larger than that at the inlet end, water flow blocked by a water plug of the movable element will push the movable element towards the inlet end, compressing the spring element and closing the water-guiding vents gradually to reduce the water flow and stabilize the water pressure thereby.
