The invention relates to a self-compensating two-way synchronous reciprocating positioning and contraposition hydraulic system, which belongs to a hydraulic transmission control technical device. A double piston rod power cylinder A (37) and a double piston rod power cylinder B (38) are both connected with an equal fluid distributor (28). The equal fluid distributor (28) is connected with a main reversing valve through a one-way valve. Two outlets of the main reversing valve (5) are in bridge connection with composite overflow valve groups (41). One outlet is connected to a hydraulic oil tank (1) through an oil filter (42), and the other outlet is connected to the hydraulic oil tank (1) through the one-way valve A (43) and a pressurized fluid source (3). The self-compensating two-way synchronous reciprocating positioning contraposition hydraulic system has the advantage that: the invention adopts the hydraulic system, can carry out self-compensating two-way synchronous reciprocating positioning ...
