    Abstract: A switching assembly for diverting fluid flow can include a pair of chambers each having a three-way valve positioned therein. An actuator, which can include a lever and one or more gears, may be coupled with each three-way valve to allow an operator to divert flow through each three-way valve by means of the actuator. The switching assembly can be coupled with one or more pressure relief valves, allowing an operator to safely replace a pressure relief cartridge by diverting flow away from the corresponding pressure relief valve without diverting flow upstream or temporarily shutting off a fluid line.

    Abstract: A device (100) for producing artificial snow, provided with a body (101) including a pressurized water supply duct (10) and a pressurized air supply duct (20), at least one spray element (130) for spraying water or a mixture of air and water, at least one control valve (140) for adjusting the pressurized water and/or pressurized air supply of the spray element, and operating elements, in the form of at least one camshaft, for operating the control valve (140). The valve (140) is placed on the pressurized water and air supply ducts (10 and 20), and includes, on the periphery thereof, a water chamber (144) for the pressurized water supply thereof and an air chamber (145) for the pressurized air supply thereof. The valve (140) also includes a fixed body (141) in the general shape of a tube defining an inner receiving region (142) wherein a movable body (142) is housed, the body being translatably movable along a translation axis.

    Abstract: A land (56) on an index member (32) disposed in the interior chamber of a manifold (38) is aligned with an actuating member (34) and thereby holds open a check valve (36) through which fluid flows into the manifold's interior chamber, through a control valve (12), and out a manifold outlet (74). At the same time, another actuating pin (42) is so aligned with a recess (58) in the indexing member (32) as to permit another check valve (44) to prevent flow through itself into the manifold chamber. When the control valve is closed, flow stops, and pressure builds up in the manifold chamber. The index member (32) is accordingly driven against the force of a bias spring (48) to a lower position, in which a lower cam-follower surface (82) engages a lower cam surface (84). That engagement rotates the index member to a position in which it permits pressure to be communicated through both check valves (36 and 44) into the manifold chamber. When the control valve (12) reopens and thereby again relieves the pressure within the manifold chamber, the return of the index member (32) to the upper position causes an upper cam-follower surface (52) to engage cam pins (54). Those pins thereby cam the index member (32) to a new position, in which it opens the left check valve (44) and allows the right check valve (36) to close. By thus alternately operating the control valve (12) between its two, open and closed positions, the system is advanced through a sequence of three different flow states.

    Abstract: A mixing valve according to the invention allows fluids such as hot and cold water to flow through a pair of inlet ports, mix together and then exit through an outlet port. A check valve in each inlet allows the incoming fluid to flow in a forward direction, but prevents any reverse or crossover flow. An adjustable stop, positioned intermediate the valves, regulates the extent to which each valve can open to provide a desired mixing ratio of fluids, and can also be used to close one of the check valves. An actuator connected to the adjustable stop permits manual control of the mixing ratio.
