  "textContent": "An oil-hydraulic vehicle comprising (i) at least one oil-hydraulic pump 10 driven by an engine E, an input shaft of said oil-hydraulic pump being directly coupled with a crankshaft of the engine, (ii) at least one oil-hydraulic motor 30 to drive at least one wheel 31 in both forward and backward directions, (iii) an oil-hydraulic circuit 50 to connect said oil-hydraulic pump 10 and said oil-hydraulic motor 30, and (iv) at least one flow control valve 60 provided between said at least one oil-hydraulic pump 10 and said at least one oil-hydraulic motor 30. Said at least one flow control valve 60 has (i) a first changeover position where the valve 60 returns the oil, which is fed from said oil-hydraulic pump 10 to the valve 60, to said oil-hydraulic pump 10, (ii) a second changeover position where the valve 60 feeds the oil, which is fed from said - oil-hydraulic pump 10 to the valve 60, to an inlet of said oil-hydraulic motor 30, and (iii) a third changeover position where the valve 60 feeds the oil, which is fed from said oil-hydraulic pump 10 to the valve 60, to an outlet of said oil-hydraulic motor 30.",
