Abstract

PURPOSE: Two hydraulic pumps and an electric motor are used to operate an eccentric rod type cylinder in a hydraulic device of a hydrostatic transmission. CONSTITUTION: Two hydraulic pumps are used to drive an eccentric rod type cylinder with an electric motor(300). A driving portion(1) comprises a first and second hydraulic pump(11,11a) in both sides of the electric motor. An accumulator passage(4) connects one port(b) of the first hydraulic pump with an accumulator(800). A head side passage(2) connects a port(c) of the second hydraulic pump with the other port of the first hydraulic pump. A rod side passage(3) connects rod side of the eccentric rod type cylinder with the other port(d) of the second hydraulic pump.
