(54) АККУМУЛЯТОР ПРУЖИННЫЙ(54) SPRING BATTERY

.. I .. I

Изобретение относитс к машинострои- гельной гидравлике и может быть использо-i рано в качестве аккумул тора энергии в: гидросистемах.;The invention relates to machine-building hydraulics and can be used early as an energy accumulator in: hydraulic systems .;

Наиболее близким по технической сущности и достигаемому результату.к предлага-. емрму вл етс аккумул тор пружинный, содержащий корпус, щтуцер, крыщку и уста новленный внутри корпуса разделительный элемент сильфонного типа J1J.The closest in technical essence and the achieved result. The thermometer is a spring battery, comprising a housing, a clamp, a cap and a separating bellows type J1J mounted inside the housing.

Недостаток этого аккумул тора - в нем ограничена возможность повышени давлени и, следовательно, ограничена энергоемкость и полезный объем.The disadvantage of this battery is that it limits the possibility of pressure increase and, consequently, reduces energy consumption and useful volume.

Цель изобретени - повышение рабочих давлений, энергоемкости и полезного объема.The purpose of the invention is to increase the operating pressure, energy intensity and net volume.

Указанна цель достигаетс тем, что разделительный элемент выполнен из соединениых между собой через прокладки тарельчатых пружин с бандажными, внутреннимн н плоскими наружными фланцами и торцовых элементов в виде крышКи с одной стороны и подвижной заглушки с нажимной сферой с другой, а демпфирующее устройство выполнено в виде тарельчатой пер.форированной шайбы, установленной на штуцере и взаимодействук щей с нажимной сферой подвижной заглушки. Кроме того, корпус снабжен направл ющими планками, установленными вдоль образующих с внутренней стороны корпуса.This goal is achieved by the fact that the separating element is made of interconnected through gaskets disk springs with retaining, internal flat outer flanges and end elements in the form of a cover on one side and a movable plug with a pressure sphere on the other, and the damping device is made in the form of a plate. perforated washer installed on the fitting and interacting with the pressure sphere of the movable plug. In addition, the housing is provided with guide rails installed along the generators on the inside of the housing.

L Аккумул тор пружииный содержит корпус 1, к которому прикреплен штуцер 2, а с другой стороны - крышка 3, котора longitudinal incision; in fig. 2 - section A-A; . in fig. one; in fig. 3 shows a section BB in FIG. L The spring-loaded battery contains a housing 1, to which a fitting 2 is attached, and on the other hand a cover 3, which

IQ вместе с тарельчатыми пружинами 4, подвижной заглушкой 5, прокладками 6 и скреп л ющими болтами 7 составл ет разделитель ный элемент аккумул тора. Тарельчатые пружнны 4 имеют бандажные внутренние 8 и плоские наружные 9 фланцы. На корпусе IIQ together with the cup springs 4, the movable stopper 5, the gaskets 6 and the fastening bolts 7 constitute the separator element of the battery. Dish spring 4 have a bandage inner 8 and flat outer 9 flanges. On the case I

15 с его внутренней стороны установлены направл ющие планки 10. На штуцере 2 закреплена тарельчата перфорированна шайба П с отверсти мн 2. На подвижной заглушке 5 выполнена нажимна сфеfpa 13 с поднутрени ми 14 (см. фиг. 2).15, guiding strips 10 are installed on its inner side. A perforated washer II with an opening of a plunger 2 is fastened on the fitting 2 of the trunnion 2. On the movable plug 5 there is a push-pull sphera 13 with undercuts 14 (see Fig. 2).

Claims

The same movable plug 5 has a threaded shank 15 coaxially with the sleeve 16 on the lid 3. The separator element ak-1 of the cumulator, together with the internal volume of the housing 1, forms the fluid cavity 17 of the battery. Battery spring torus works as follows. When charging the battery through the nozzle 2, the excessive pressure of the fluid acts on the cup springs 4 and the movable cap 5 and causes the compression of the entire separating element. At the same time, the volume of the Andkost cavity 17 increases. In the process of discharging the battery during steam; The pressure in the hydraulic network is reversed. When fully discharged, the pressure sphere 13 comes into contact: with a disc perforated washer 11. flpH This is at the initial moment the fluid is perforated; {re-enters into choke 2, the passage is all from er-1n 12. With a further rise of the stub .5 the pressure sphere. 13 squeezes the perforated plate washer-P, which, due to its elasticity, "rolls along the surface of the said sphere and passes to the contact line from the ıt of a smaller diameter with successive overlap of the holes 12. Due to this, the flow rate and the rise of the total separator element decrease || enta, which contributes to the reduction of shock loads when the battery is discharged. In the extreme position of the separating element, the liquid cavity 17 is connected to the hydraulic network through the inner holes 12 and the undercuts 14 and the pressure sphere 13. For drying and separating the separating element, the cup springs 4 are compressed by means of a shank 15, into which the springs are wrapped (see fig. not shown) in the form of a bolt that passes through sleeve 16. This installation after dismantling CH Maefi c, and the hole in sleeve 16 is muffled. The use of the proposed accumulator excludes the use of The piston element, which has, especially at high pressures, an insufficient ability to resist leakage and pressure drop in the fluid cavity during prolonged standing, and allows for an increase in operating pressures, energy consumption and useful battery volume. Claim 1. The accumulator is spring-loaded, comprising a housing, a choke, a lid and a separating element of the bellows type installed inside the housing, characterized in that, in order to increase the working pressure, energy intensity and useful volume, the separating element is made of interlocking springs connected to each other with retaining, inner and flat outer flanges and end elements in the form of a lid on one side and a movable plug with a pressure sphere with a FRIEND damping device performed in the form of tar perforated velchatoy washers installed on the nozzle and interacting with the pressure sphere of the movable plug.

2. The accumulator according to claim 1, characterized in that the housing is provided with guide rails installed along the generators formed on the inner side of the housing. Sources of information taken into account during the examination 1. US Patent No. 3.422.753, cl. 138-30, published. 1965.
