ABSTRACT:
A hydraulic pump for vehicles controllable by handlebars, having an unusually small space requirement, including a reservoir suitable for containing a working fluid having a free surface at the top, a pump body provided with a wall which delimits a cavity, and also freely conveying the fluid from the reservoir to the cavity of the pump body through an opening provided in the wall of the pump body. The opening is provided in a portion of the wall of the pump body at a distance from the top thereof, so that, during the operation of the pump, the free surface of the fluid contained in the reservoir is able to fall below the top without the fluid exposing the opening.
