Title:
MANUAL HYDRAULIC ACTUATION DEVICE
Document Type and Number:
Japanese Patent JP2022151216
Kind Code:
A
Abstract:
To provide a manual hydraulic actuation device which reduces a force required for that an operator moves a control lever when a force against movement of an operation part performed by operating the control lever is given to the operation part, and consequently, can reduce load of the operator.SOLUTION: A manual hydraulic actuation device (for example, cutting device 10) comprises a body part 20, a tool 30 having an operation part (for example, a pair of cutting components 31), and a control lever 24 operated by an operator. When the control lever 24 is operated by the operator, a piston 50 moves, and consequently, a pressure oil passes through an oil passage and moves between a plurality of oil sacs, whereby a slide member 34 is moved. When a force against movement of the operation part performed by operating the control lever 24 is given to the operation part, an amount of the pressure oil, which is fed to one of the plurality of oil sacs in order to move the slide member 34, decreases.SELECTED DRAWING: Figure 3
