Description
Изобретение касаетс гидравлических домкратов с диференциальным насосом, в которых, с целью облегчени монтажа последних, предлагаетс примен ть упорную планку, помещенную в масленой коробке насоса и снабженную пробкой, допускающей доступ к клапану насоса, при чем пробка в то же врем вл етс упорным стаканом дл одного из концов насоса.The invention relates to hydraulic jacks with a differential pump, in which, in order to facilitate the installation of the latter, it is proposed to use a stop bar placed in the oil box of the pump and provided with a stopper allowing access to the pump valve, while the stopper is one of the ends of the pump.
На чертеже изображен проДольньш осевой разрез предлагаемого домкрат а.The drawing shows a relatively axial section of the proposed jack a.
К телу домкрата 1 при помощи винтовой нарезки присоединен диференциальный насос, упираемый другим концом в упорный стакан или пробку 20, ввинченную в упорную планку 18. Последн заводитс в выступы 19 масленой коробки 3, прикрепленной к телу домкрата (см. черт.). При движении, посредством рычага с кулачками 17 плунжера 5, из правого крайнего положени влево, жидкость из камеры 10 через клапан 11, каналы 12 и 13 нагнетаетс в рабочую полость 14 домкрата; одновременно через клапан 16 и канал 15A differential pump is attached to the body of the jack 1 by means of a screw thread, abutting the other end against the thrust cup or plug 20 screwed into the stop bar 18. The latter is inserted into the lugs 19 of the oil box 3 attached to the jack body (see fig.). When moving, by means of a lever with cams 17 of plunger 5, from the right extreme position to the left, fluid from chamber 10 through valve 11, channels 12 and 13 are injected into the working cavity 14 of the jack; simultaneously through valve 16 and channel 15
в камеру 6. засасываетс жидкость из коробки 3. При обратном движении плунжера 5 жидкость из камеры 6, под давлением правого конца ттоследнего, через клапан 7, канал 8 и клапан 9 поступает в камеру 10, при чем избыток жидкости переходит в полость 14 домкрата. Таким образом, при движении вправо и влево жидкость нагнетаетс в полость 14, поднима рабочий плунжер 2 домкрата (см. чертеж).into the chamber 6. fluid is sucked out of the box 3. When the plunger 5 moves back, the fluid from chamber 6, under pressure from the right end of the latter, through valve 7, channel 8 and valve 9 enters chamber 10, at which excess liquid passes into cavity 14 of the jack. Thus, when moving right and left, the fluid is injected into the cavity 14, raising the working plunger 2 of the jack (see drawing).
Предмет патента.The subject of the patent.
Гидравлический домкрат с диференциальным насосом, характеризующийс применением упорной планки 18, заводимой в выступы 19 масленой коробки насоса 3 и снабженной посередине отверстием с винтовой нарезкой дл ввинчивани пробки 20, облегчающей доступ к клапану 7 и вл ющейс упорным стаканом дл одного конца диференциального насоса, присоединенного другим концом с помощью винтовой нарезки к телу домкрата.A hydraulic jack with a differential pump, characterized by the use of a stop plate 18, inserted into the projections 19 of the oil box of the pump 3 and provided with a screw-thread hole in the middle for screwing in the plug 20, facilitating access to the valve 7 and being a stop plate for one end of the differential pump connected to the other end with a screw thread to the body of the jack.
