Abstract: A manifold is provided. The manifold includes: a first body having an outer surface; a second body having an inner surface corresponding to the outer surface of the first body and the first body is micro-welded to the second body; and a groove formed in one or both of the outer and inner surfaces, wherein the first body is dimensioned to fit within the second body so that the outer surface contacts the inner surface and the groove forms a fluid passage located between the first and second bodies, the fluid passage having an inlet and an outlet. Also in some embodiments a method of forming a manifold is provided. The method includes: filling a die with powdered metal having grains; compressing the powdered metal in the die thereby forming a first body; removing the compressed part from the die; contacting the first body to a second body subjecting the bodies to heat; and forming micro-weld between grains of metal between the two bodies.

Abstract: An adjustable cooling mechanism is provided. The cooling mechanism may include: a hollow member surrounding, at least in part, a machine to be cooled; the hollow member having holes oriented at the machine; an outlet configured to outlet a compressed fluid from the machine; a conduit connecting the outlet to an interior of the hollow member; and a throttling mechanism configured to throttle a fluid moving through the holes.

Abstract: A hydraulic device includes a hydraulic pump, valve stack, interface tube, and upper and lower seals. The valve stack has a pressure balanced connecting with an interface tube receiving bore. The interface tube conveys a hydraulic fluid from the hydraulic pump to the valve stack and has an axial bore open at a first end and closed at a second end with an outlet proximal to the second end. The upper seal seals the interface tube in the interface tube receiving bore and is disposed annularly about the interface tube between the outlet and the second end. The lower seal seals the interface tube in the interface tube receiving bore and is disposed annularly about the interface tube proximal to the outlet and between the outlet and the first end. The upper seal and the lower seal balance a pressure of the hydraulic fluid from the outlet.

Abstract: A compressed gas powered machine is provided. The machine includes: an outlet and a hollow member fluidly connected to the outlet and configured to receive gas expended from the machine through the outlet the hollow member defining holes oriented to allow the gas contained in the hollow member to blow on various parts of the machine.

Abstract: A cooling system and method are provided to cool a working fluid in an inner tank. The cooling system includes an outer tank and a gap formed between the inner tank and outer tank. The cooling system further includes a baffle disposed in the gap to damp a flow of a cooling liquid that is introduced into the gap. The baffle is designed to decrease the noise and turbulence that can occur with the introduction of the cooling liquid into the gap.
