Title: Auto-tensioner device
Inventor: MIYAMOTO KOJI
IPC: B66C13/22
Filed: 1987-12-24
Abstract: PURPOSE: To effectively absorb snap load acting on a cable at the time of landing on the water and from the water by providing a switching valve which directly flows hydraulic fluid without going by way of a flow regulating valve. CONSTITUTION: When tensile force of a cable 1 is rapidly increased, an oscillation amount detection cylinder 2 contracts from a maximum elongating location. At this time, a fixed restriction 12B of a control valve 12 resists hydraulic fluid flowing out from the cylinder part 2B to an oil chamber 11A of a second accumulator 11. The contracted oscillation amount detection cylinder 2 elongates again because hydraulic fluid of the oil chamber 11A of the second accumulator 11 flows in the cylinder part 2B from a check valve 13B without resistance when tensile force of the cable 1 is lowered. When tensile force of the cable 1 is reduced, a ram cylinder 3 of a most compressive state or the adjacent state elongates by air pressure of a first accumulator 19.  In this case, hydraulic fluid flowing in the ram cylinder 3 from an oil chamber 19A passes a check valve 18B installed in a flow regulating valve 18 without resistance.
