Sampling devices working fluid from the hydraulic system

摘要

The invention relates to a device for selecting a working fluid samples from hydraulic and can be used in the aviation and other industries that use the working fluid under high pressure. The apparatus comprises a housing 1 with a connection 2 for connection to the hydraulic system, the spring-loaded valve 3 comprising a closure member 4 rigidly connected to the casing 1 and the seat 5, arranged in the sleeve 6 mounted in the housing 1 axially moving it relative to the lock body 4. at the bottom of the sleeve 6 arranged outlet conduit 15, which accommodates the hollow needle 16 cooperating with the elastic cover 17, the receiving container 18. By pressing the handle 13 of the sleeve 6 is displaced downward, opening the shut-off valve 3, simultaneously with the needle 16 n rokalyvaet elastic cap 17 and the fluid flows through the opening in the needle 16 into the vessel 18. With the needle mount 16 relative to the movable body 1 and the sleeve 6 fixed on the body 1 locking container 18 is guaranteed coaxial relative to the container 18, the movement of the needle 16, which excludes its exit from system and simplifies the conditions of work with the device.
