ABSTRACT:
An hydraulic system comprising a displacement-type hydraulic element in communication with a sealed reservoir tank for receiving hydraulic fluid from and returning hydraulic fluid to the reservoir, and a stabilizer for preventing excessive vacuum and pressure from forming within the reservoir as fluid is moved into and out of the same. The stabilizer is carried within the reservoir tank and has a bellows construction for compensating for change of volume in the reservoir as fluid changes take place therein, and the stabilizer is vented to the atmosphere through a breather system constructed to minimize entrance of dirt and the like within the stabilizer.
