Fluid distribution valve

A fluid distribution valve comprising,

• a base member having a fluid inlet and a series of fluid outlets therein,
• a valve plate having an inlet opening and a series of valve seat openings disposed on said base with corresponding openings in alignment,
• a series of valve members disposed adjacent said valve seat openings for closing and opening same,
• a piston housing member having a series of chambers corresponding to said valve members disposed on said base and spaced from said valve plate to form a flow compartment,
• a series of two sided pistons one each of which is disposed in each chamber of said piston housing, each of said pistons being connected to one of said valve members for operating same,
• a cover member disposed on said base member over said piston housing and with said piston housing defining a control compartment,
• first openings connecting said flow compartment and said control compartment,
• second openings between one side of each of said two sided pistons and said flow compartment,
• third openings between the other side of said two sided pistons and said control compartment,
• means for controlling said third openings between an open state and a closed state,
• an impeller in said flow compartment adjacent said inlet opening and adapted to rotate upon flow through said inlet opening,
• gear mechanism in said control compartment connected to said impeller, and
• means operated by said gear mechanism in response to rotation of said impeller for sequentially actuating said controlling means.

A fluid distribution valve comprising:

• a flow chamber and a control chamber separated from each other,
• a fluid passage from said flow chamber to said control chamber,
• filter means disposed in said fluid passage for filtering control flow,
• inlet flow means to and a series of outlet flow means from said flow chamber,
• a series of valve means one each being in each of said series of outlet flow means and being adapted to close against the pressure in said flow chamber, and
• means controlled by the pressure in said control chamber for sequentially closing the valves of said series of valves against the pressure in said flow chamber.

A fluid distribution valve comprising:

• a base member having an inlet port and a series of outlet ports for attachment to plumbing connections,
• a removable valve module member having an inlet port, a series of outlet ports and valve operating components disposed therein,
• said module member being disposed in said base member with the inlet port and the outlet ports in registration with each other, respectively,
• a non-plumbing connection cover member attached to said base member, and
• said removable valve module member including piston housing members, a series of two sided pistons, a flow chamber in combination with said base member, a control chamber in combination with said cover member, fluid passages from said flow chamber to said control chamber, and filter means disposed in said fluid passages.
