Directional poppet valve

A directional poppet valve, comprising:

• a valve housing having first, second, third and fourth valve connections and having first, second, third and fourth valve seats;
• first, second, third and fourth valve pistons movably disposed in said valve housing and controlling said first, second, third and fourth valve connections, respectively, said valve pistons being in sequence one after another along an axis and being interengaged in first and second pairs of said first and second valve pistons and said third and fourth valve pistons, respectively, each of said pairs being disposed between two of said valve seats;
• first and second actuating rods being axially movable in said valve housing along said axis and extending through said valve pistons with each of said valve pistons being axially movable and guided on said actuating rods along said axis, said first and second valve pistons being on said first actuating rod, said third and fourth valve pistons being on said second actuating rod, said first and second actuating rods at least partially intermeshing one another in said valve housing for independent movement thereof, with each of said actuating rods forming part of an actuation device exerting an actuation force in one of two opposite directions on each of the respective actuating rods;
• first, second, third and fourth piston actuators, said first and second piston actuators being fixed on said first actuating rod and contacting to move said first and second valve pistons from said first and second valve seats, respectively, said third and fourth piston actuators being fixed on said second actuating rod and contacting to move said third and fourth piston valves from said third and fourth valve seats, respectively, said first and second valve pistons being between said first and second piston actuators limiting axial movement of said first and second valve pistons relative to said first actuating rod, said third and fourth valve pistons being between said third and fourth piston actuators limiting axial movement of said third and fourth valve pistons relative to said second actuating rod;
• and
• first and second resetters coupled to said valve pistons of said first and second pairs, respectively, and biasing each said valve piston toward a respective one of said valve seats, each said resetter being in a chamber in the respective piston valves interengaging with each other, each said valve piston engaging the respective valve seat under biasing of the respective setter in a non-actuated and central position of said actuating rods.
