Model		Pump type
Regulation of pressure of a liquid	Working pressure	6500 кПа (65 kg/sm², 924 psi) — for engine G16 7000 кПа (70 kg/sm², 995 psi) — for engine J20
	The supervising device	The account valve
		The reduktsionnyj valve
The relay of pressure of the hydraulic booster of a wheel		The relay joins (is closed) when pressure exceeds 2500 – 3500 кПа (25 – 35 kg/sm², 356 – 498 psi). The engine management block uses this signal for idling regulation.
Capacity		0.70 – 0.75 l
Applied liquid		DEXRON ® II, DEXRON ® III liquid for АКПП or equivalent

The account valve

Unloading of the pump of the hydraulic booster proportionally increases pump turns, the account valve, is applied here to regulation of giving of optimum quantity of a liquid according to engine turns.

Work of the account valve is more low resulted at various speed of the engine.
