Abstract

Improved hydraulic press, of the type that has two vertical columns that start from a base of support, joined at the top by a solid crossbar and that have a crossbar parallel to the previous one, susceptible to be fixed at different heights on the columns, with the upper crossbar associated with the hydraulic cylinder, the piston rod of which, at the bottom, has an adjustable attack end by coaxial screw by rotation, characterized in that the pump, located laterally and close to the upper part, is formed by an assembly enclosed by an enclosure that constitutes a reservoir for the functional liquid, the main part of said pump being a parallelepiped block in which two parallel longitudinal ducts are drilled, one of which forms part of the cylinder, said ducts being interconnected by a perpendicular one, the admission being carried out at the lower end of the extension. Cylinder or, there having interposed a ball acting as a check valve, by gravity, while the parallel conduit opens only to the opposite end, in which the output fitting is screwed, with a ball check valve assembly, of the same as the previous one, but loaded by means of a spring, said welded plug having a perpendicular fastening plate, a lateral lever fork of the actuating lever and, in opposition to said fork, a tubular outlet, blocked by a ball, pressed against its seat by means of a screw, there being a radial lower bore after said ball for free discharge once the said screw is loosened.
