Abstract

Improved hydraulic pump, which is characterized, because the pump body, of cylindrical nature, with the inlet and outlet holes of fluids, offers a point, between both orifices, of a valve, integrated by a plate bent in the form of obtuse angle, of unequal branches, and whose greater branch comes to close the exit orifice, located in the bosom of a cajeado in which the branch perfectly fits, this valve being subjected to the action of a small spring that acts wound in its axis of tilt of the valve, and whose action tends to keep the valve separated from the outlet orifice, and supporting the end of said greater branch on the body of the central piston, whose section has the shape of a cam, and whose tapered end offers a reembiable piece, to maintain at all times a perfect and tight contact with the walls of the cylindrical body, which in its turn travels, pushing forward the liquid absorbed in the anterior ci at the same time, absorbing, through the vacuum created in its turn, the liquid that penetrates through the inlet, closing the valve the exit orifice when the end of the piston-cam pushes the valve taking it to the slot in which that orifice opens, and returning it to open, when that has exceeded the point of tilt of the valve, now pushing the smaller arm of it, and tilting again to verify the opening of the exit orifice.
