Abstract: A system for controlling plurality of pistons in a corresponding plurality of actuators comprises a pump, a tank and a cylindrically shaped valve. The cylindrically shaped valve comprises an outer hollow cylinder with a first, a second, a third and a fourth set of holes, and the inner cylinder with a cylindrical base, and having a first and a second set of non-overlapping spiral grooves that are parallel to each other, in that the first set of holes are at different distance from the cylindrical base, the third set of holes maintain one to one correspondence with the first set of holes at 180 degrees opposite, the second set of holes maintain one to one correspondence with the first set of holes at same distance in a straight line, 180 degrees, the fourth set of holes maintain one to one correspondence with the second set of holes, 180 degrees opposite.

Abstract: According to an aspect of the present invention, multi nozzle device comprises hollow inner cylinder and an outer cylinder. The hollow inner cylinder may have multiple nozzles along the length of said inner cylinder. The hollow inner cylinder may be coupled to a first pressure. The outer cylinder may be mounted over said inner cylinder such that internal diameter of said outer cylinder is in push fit with external diameter of said inner cylinder. The push fit is chosen to minimize friction to enable the outer cylinder to take place of the flapper. The outer cylinder is moved exposing the nozzles and the first pressure is reduced by a proportion related to number of nozzles exposed. In one embodiment, multi nozzle device further comprise, an O ring to prevent leakage of pressure when the inner cylinder and the outer cylinder are tight fit.

Abstract: In one aspect of the present invention carburetor comprises a hollow first cylinder and a hollow second cylinder. In one embodiment, hollow first cylinder comprising plurality of nozzles formed on the lateral surface and nozzles providing flow path for a fuel to flow from the hollow region to outside of the later surface of the first cylinder. In another embodiment, hollow second cylinder placed on the first cylinder and the axis of the first cylinder and the second cylinder coincide. In another aspect of the present invention, sliding the second cylinder over the first cylinder, and number of nozzles through which fuel flows out increases when the outer cylinder is slide in first direction. In one embodiment, the first cylinder is placed in a first region through which air is sucked into the combustion chamber. In another embodiment, a throttle control operative to increase the engine power, may be coupled to the second cylinder such that increasing throttle pulls the second cylinder in the first direction.

Abstract: According to first aspect, a flow control valve comprises outer hollow cylinder and an indexing member. The hollow cylinder comprises a pressure port, a tank port, a first port and a second port on the curved surface. The indexing member comprises an inner cylinder, and is fit to the hollow part of the outer cylinder. When the inner cylinder is at a first relative position with the outer cylinder, the pressure port is connected to the first port and tank outlet is connected to the second port. When the inner cylinder is at a second relative position with the outer cylinder, the pressure port is connected to the second port and tank outlet is connected to first port. According to another aspect, a system for controlling a movement of a piston in an actuator may comprise an indexing valve, an actuator and a pump. The actuator comprises piston and piston rod. The indexing valve comprises outer cylinder and indexed inner cylinder. The pump is used to inject pressurized fluid.
