ABSTRACT:
A hydraulic apparatus such as a bleeder screw comprises an inner end, an outer end, and a main body extending between the inner end and the outer end. The main body includes a first section having a threaded outer peripheral surface a second section disposed between the first section and the inner end. The second section has a smaller diameter than the threaded outer peripheral surface of the first section, and an axial length of the threaded outer peripheral surface is less than an axial length of the second section. An internal fluid passage opens through an outer peripheral surface of the second section at a location between the inner end and the threaded outer peripheral surface, and the internal fluid passage opens through the main body at a location between the threaded outer peripheral surface and the outer end. Another hydraulic apparatus comprises a first fluid reservoir having a first reservoir chamber and a first reservoir outlet; a second reservoir having a second reservoir chamber and a second reservoir outlet; and a common fluid passage in fluid communication with the first reservoir outlet and the second reservoir outlet to flow fluid from both the first reservoir chamber and the second reservoir chamber to the atmosphere.
