Title:
FLUID COUPLING
Document Type and Number:
Japanese Patent JPS5493760
Kind Code:
A
Abstract:
PURPOSE:To perform revolution transmission corresponding to constant speed revolution and temperature by arranging an apparatus for bypassing fluid according to the centrifugal revolving force above a fixed value and an apparatus for opening and closing a fluid passage according to the outside temperature. CONSTITUTION:When a rotor 5 arranged in a housing 4, 8 is revolved, fluid is taken into from a fluid inlet part 15 by the action of the vane 14 in a pump chamber 12 and discharged to a fluid exit part 16. The fluid having been discharged is introduced to a second opening 23 through a passage 24. As a liquid lock apparatus 18 closes the passage due to a spring 22, fluid is pressurized highly, and revolution is transmitted to the housing 4, 8 from a shaft 1. When the number of revolution increases above a fixed value, the passage is opened by the revolving centrifugal force, and the revolution force is not transmitted. When the temperature increases, the hole of the fluid exit part 16 closes is by the lever valve of a thermo element 25, and the revolution force is transmitted.
