<p>PURPOSE:To securely send pressured oil to a hydraulic system by providing an inside partition and an outside partition, both of which open in the horizontal direction, around ports that connect a cylinder chamber to a reservoir tank, and also providing a connecting means through which the inside and outside of the tank are connected. CONSTITUTION:In a reservoir tank 5, an inside partition part 22, which opens up rightwards, is provided around the top-end openings of a supply port 7 and a relief port 8, while an outside partition part 23, which opens up leftwards, is provided around the inside partition part 22. The capacity of the inside partition part 22 is set to be equal to or slightly greater than the volume that can be removed by one stroke of a master piston 13. Also, one end 11a of a connecting pipe 11 is connected to nearly the center of a tank cap 9 to connect the inside of the reservoir tank 5 to the outside through the opening of the other end 11b of the connecting pipe 11.</p> |
