RECUPERATOR Russian patent published in 2011 - IPC B60K6/00 

FIELD: transport.

SUBSTANCE: proposed recuperator comprises gear pump 1 fitted via overrunning coupling 2 is fitted on drive shaft and articulated with vehicle wheels and, via pipelines and mechanical power accumulating hydraulic cylinder 4, with pedal of brake 6. Recuperator comprises control valve 5 cut in at intersection of pressure and drain pipelines of hydraulic cylinder 4 and gear pump 1 and coupled with aforesaid brake pedal to allow fluid to circulate via gear pump 1 solely in one direction. In braking, brake pedal with control valve 5 allows forcing fluid into hydraulic cylinder 4 via extreme channels of control valve 5 by gear pump 1. Thus, power is accumulated in hydraulic cylinder 4. Gear pump 1 is driven by drive shaft when braking system extra hydraulic cylinder acts thereon via friction coupling 3. Note that gear of dear pump 1 is driven by drive shaft overrunning coupling 2. Fluid is forced into hydraulic cylinder 4 for recuperator to be charged.

EFFECT: simplified design and higher efficiency.
