Improvements in the piston pumps, characterized in that the pump body, comprises a housing where are inserted some sockets corresponding to the suction and delivery valves, being inside between the sockets of both valves, an air chamber of reduced dimensions, whose volume is significantly lower than the volume of the piston that alternately produces the aspiration and impulsion of the liquid, in order that, because the piston is larger than the small air chamber, an immediate suction is produced.
