<p>To simplify the production of the casing and of the pump overall in a hydraulic pump with a working plunger (3) actuable by a lever (4) articulated on the said plunger, an inlet valve (22, 27) for feeding a working cylinder accommodating the working plunger with hydraulic fluid is placed in the base of the bore (2) of the working cylinder and an outlet valve (20, 26) for the discharge of the hydraulic fluid under pressure from the working cylinder is placed in the working plunger. In addition, some of the bores (9, 17, 21, 24) for guiding the hydraulic fluid which are required in the casing (1) apart from the bore (2) of the working cylinder are executed parallel to the bore of the working cylinder and some of them are executed perpendicularly thereto, and as far as possible coaxially to one another. <IMAGE></p> |
