Description

В предлагаемом гидравлическом домкрате, с целью повышени  развиваемого им усили  без повышени  давлени  рабочей жидкости и без увеличени  диаметра поршн , шток поршн  соединен с днишем стакана, охватываюпдего рабочий цилиндр Домкрата, так, что между днищами стакана и рабочего цилиндра образована дополнительна  камера, в которую подаетс  рабоча  жидкость. Подача этой жидкости осуществл етс  через канал в штоке поршн .In the proposed hydraulic jack, in order to increase the force developed by it without increasing the pressure of the working fluid and without increasing the diameter of the piston, the piston rod is connected to the bottom of the glass, covering the working cylinder of the Jack so that an additional chamber is formed between the bottoms of the glass and working cylinder working fluid. This fluid is fed through a channel in the piston rod.

На чертеже показан описываемый домкрат в разрезе.The drawing shows the described jack in the section.

Домкрат состоит из рабочего цилиндра / с образующим рабочую полость А порщнем 2, шток 3 которого имеет осевой канал 4 и соединен с днищем стакана 5, охватывающего рабочий цилиндр, так, что между днищами стакана и рабочего цилиндра образована дополнительна  камера Б, в которую подаетс  рабоча  жидкость из камеры Л через осевой канал 4 и радиальные каналы 6 в штоке 3. Подвод жидкости в рабочую камеру А осуществл етс  через штуцер 7 в наружной крышке рабочего цилиндра. Внутренн   полость В между поршнем и днищем цилиндра сообщена с атмосферой через трубку 8, монтированную в осевом канале штока.The jack consists of a working cylinder / forming the working cavity A with a pressure 2, the rod 3 of which has an axial channel 4 and is connected to the bottom of the glass 5 covering the working cylinder, so that an additional chamber B is formed between the bottoms of the glass and the working cylinder the fluid from the chamber L through the axial channel 4 and the radial channels 6 in the rod 3. The liquid is supplied to the working chamber A through the nozzle 7 in the outer cap of the working cylinder. The internal cavity B between the piston and the bottom of the cylinder communicates with the atmosphere through a tube 8 mounted in the axial channel of the rod.

При таком устройстве усилие, развиваемое домкратом, складываетс  из давлени  рабочей среды (жидкости или воздуха) на кольцевую поверхность поршн  и давлени  на внутреннюю поверхность дниша стакана 5.With this device, the force developed by the jack is added up from the pressure of the working medium (liquid or air) on the annular surface of the piston and the pressure on the inner surface of the bottom of the cup 5.
