Abstract

The invention relates to hydraulic actuators and can be used in hydraulic systems for smoothing pressure pulsations. The purpose of the invention is to simplify the design and reduce the dimensions of the hydraulic accumulator by placing the charging device inside it. Separator 4 is placed in housing 1 with a lid 2 and a charging neck 3. Separator 4 is made in the form of a spring-loaded piston with an axial bore 9. Charger 6 of the charging device 5 is made in the form of a stepped slide valve that passes through the aperture 9 and interacts with the throat of the 3rd stage 10 smaller diameter. Step 10 is equipped with throttling slots 11. The cover 2 is located on the side of the spring 12, is made stepped, it has a step 13 of larger diameter with the formation of the control cavity 14. The cavity 14 communicates with the hydroline 7 of the consumer 8 through a three-position distributor 15. A controlled choke 16 is installed between the cavity 14 and the distributor 15. 1 Cp f-ly, 1 ill.

and the charge port 3 accommodates the separator (4. The separator b is made in the form of a spring-loaded piston with an axial bore 9. The choke 6 of the charging device 5 is made in the form of a stepped spool, passing through the bore 9 and interacting with the neck 3 with a level 10 of smaller diameter. Stage 10 is equipped with throttling slots 11, Lid 2 location The invention relates to hydraulic actuators and can be used in hydraulic systems where it is necessary to smooth the pressure pulsation.

The aim of the invention is to simplify the design and reduce the size by placing the charger inside the battery.

The drawing shows a constructive diagram of the hydroaccumulator "

The hydroaccumulator includes a housing 1 with a lid 2 and a charging neck 3, a separator located therein, a charging device 5 with an adjustable throttle 6 and a consumer line 8 7 connected to it. Separator A is designed as a spring-loaded piston with an axial bore 9. Throttle 6 The charging device 5 is made in the form of a stepped spool passing through the piston hole 9 and interacting with the charging neck 3 in a step 10 of smaller diameter, equipped with throttling slots 11. The cover 2 is located on the side of the spring 12, not staggered and placed in it a step 13 of a larger diameter with the formation of the control cavity communicated with the hydroline 7 of the consumer 8 through the three-position valve 15. An additional controlled choke 16 is installed between the control cavity 1 and the valve 15.

The hydroaccumulus torus operates as follows.

In the middle position of the distributor 15, the working fluid in the control cavity is locked and the spool of the charging device 5 is stationary, is in a predetermined position and provides the necessary rigidity of the hydraulic line.

In the right-hand position of the distributor 15, the control cavity

the wife on the side of the spring 12 is stepped; it has a step 13 of a larger diameter with the formation of a control cavity. Cavity And communicated with hydroline 7 consumer 8 through a three-position distributor

communicated with the drain and the goldworker moves down, reducing the resistance of the throttle 6 and the rigidity of the hydraulic drive.

In the zero position of the distributor 15, the cavity 1 communicates with the pressure line 7 of the consumer 8, and due to the fact that the area of the step 13 is larger than the area of the step 10, the spool moves upwards, increasing the resistance of the throttle 6 and the rigidity of the hydraulic drive.
