A switch device with multiple water outputs includes a switch valve, a rotary rod, an engagement ring, a first rotary plate and a second rotary plate. The rotary rod is mounted through an opening of the switch valve. The engagement ring has an inner toothed ring and an outer toothed ring formed on a bottom end of the rotary rod. The first rotary plate and the second rotary plate respectively engage the inner toothed ring and the outer toothed ring, and the both rotary plates have multiple holes. As water entering the holes with different number and deviation angle of the first and second rotary plate selectively communicate with each other, different water outputs can be provided.

The invention relates to an apparatus and method for providing a plurality of metered service lines to a residential utility system wherein one of the service lines may be independently disabled without affecting the other service lines.

There is provided a valve structure including a valve case provided with a suction port and discharge ports, valve bodies provided for opening and closing the discharge ports and a drive body for driving the valve bodies, where the valve bodies are provided with, at one end thereof, a blocking portion for closing the discharge port and at the other end thereof, an elastic member portion generating an elastic force for moving the blocking portion for opening and closing the discharge port, the rod-like drive body having a convex portion on its side is inserted into through-holes provided on the valve bodies in a direction intersecting a moving direction of the blocking portion moved by an elastic force, and the blocking portion is moved in the direction intersecting the drive body by the rotation of the drive body, thereby controlling the opening and closing of the discharge port.

The invention relates to a micro pilot valve 1, which is characterized by a micro cavity 2, which is connected with valve outlet 3, a first micro opening 4 between micro cavity 2 and a first pressure level 5, a second micro opening 6 between micro cavity 2 and a second pressure level 7, a sealing element 8 within micro cavity 2, which is movable between the micro openings, and which in a first end position closes micro opening 4 and in a second end position micro opening 6, whereas the control pressure in the first end position adopts the value of the second pressure level 7 and in the second end position the value of the first pressure level 5, and a micro actuator 10, which actuates sealing element 8 via a transfer element, which protrudes at least through one of the micro openings.

An adapter for a pool cleaning system is provided. The adapter includes a base member having a top and a bottom surface. The adapter also includes six upper ports coupled to the top surface of the base member, each upper port including an upper aperture extending through the upper port and through the base member. The adapter further includes five lower ports coupled to the bottom surface of the base member, each lower port including a lower aperture extending through the lower port and through the base member. In some embodiments, four of lower ports are in fluid communication four of the upper ports and one of the lower ports is in fluid communication with two of the upper ports.

A wearless water distribution valve directs a flow of water through a swimming pool cleaning system and includes a housing having an inlet, outlets, and an inner surface bounding and defining an interior coupled in fluid communication with the inlet and the outlets. The valve further includes a disc having a port, and being mounted for rotation in the housing for movement among a plurality of positions, each position of the disc characterized by the port being aligned with a respective one of the outlets. The valve further includes a drive assembly carried by the housing and operably coupled to impart rotation to the disc. In response to application of the flow of water into the housing, actuation of the drive assembly imparts rotation to the disc through the plurality of positions. The disc is disposed in spaced relation away from the inner surface of the housing.

A run selection mechanism is provided for selectively directing the flow of particulate material from an air cart. The mechanism includes a chute for receiving metered particulate material. The chute has an output. A first primary conduit has an output communicating with a first pneumatic primary run and a second primary conduit has an output communicating with a second pneumatic primary run. A selector selectively directs the metered particulate material to one of the output of the chute, the first pneumatic primary run and the second pneumatic primary run.

Systems, methods, and devices are described for providing a brace having an inflation control. The control directs fluid flow from an inflation component to one or more inflatable cells of the brace. The inflatable cells are independently inflated and deflated by the inflation component through the control. The control allows a user to create a fluid path between the inflation component and one of the inflatable cells by positioning the control in an orientation corresponding to the desired inflatable cells. Each inflatable cell is independently inflated and deflated in various orientations of the control.

There is provided a multi-directional selector valve which makes it possible to control opening and closing of the discharge ports in an easy manner and to minimize increase in cost and size even if the number of branches is increased. The multi-directional selector valve includes a valve case provided with a suction port and at least two discharge ports, at least two valve bodies provided for opening or closing the at least two discharge ports, a drive body formed into a rod-like shape and provided for driving the valve bodies and a drive source for rotating the drive body, and is configured such that any of convex portions provided on the side of the drive body are pressed onto any of the at least two valve bodies by the rotation of the drive body, thereby opening or closing the at least two discharge port in order.
