Abstract:
A hydraulic device of the present invention includes: a cylinder body (S) including a cylinder ( 1 ) and a rod ( 2 ) that moves retractably inside the cylinder ( 1 ); and a pump unit ( 30 ) that is formed with an oil passage ( 31 ) and discharges, at an intermediate position in the oil passage ( 31 ), liquid into the cylinder ( 1 ) through driving of a motor (M). The cylinder body (S) is connected to the pump unit ( 30 ) via an extension ( 40 ) having an oil passage ( 41 ) that provides communication between the oil passage ( 31 ) of the pump unit ( 30 ) and an interior of the cylinder ( 1 ).

Claim (Index 7):
The hydraulic device according to  claim 1 , further comprising:\n an outer cylinder accommodating the cylinder; a tank formed between the cylinder and the outer cylinder, the tank accommodating liquid; a piston passage provided in the piston, the piston passage being configured to allow only passage of the liquid from the contraction-side chamber to the expansion-side chamber; a valve case closing one end of the cylinder, the valve case having an inlet passage that is configured to allow only passage of the liquid from the tank to the contraction-side chamber; the oil passage member including a pump that supplies the expansion-side chamber with the liquid from the tank via the oil passage of the extension, and a motor that drives the pump; and a liquid pressure circuit, wherein the liquid pressure circuit includes:\n a first bypass passage that allows only passage of the liquid from the expansion-side chamber to the contraction-side chamber; \n a first on-off valve provided at an intermediate position in the first bypass passage; \n a second bypass passage that allows only passage of the liquid from the contraction-side chamber to the tank; \n a second on-off valve provided at an intermediate position in the second bypass passage; \n an exhaust passage connecting the expansion-side chamber to the tank; and \n a variable relief valve provided at an intermediate position in the exhaust passage, the variable relief valve being possible of valve opening pressure adjustment.
