ACCUMULATOR, HYDRAULIC CONTROL SYSTEM AND MACHINE WITH ACCUMULATOR, AND METHOD OF GEAR SHIFTING Russian patent published in 2017 - IPC F16H59/02 F15B15/02 F15B15/24 

FIELD: machine engineering.

SUBSTANCE: accumulator comprises a body, a piston. The piston has a piston rod, a first piston disc and a second piston disc, a spring for engagement with the piston. The first piston disc and the body define together the first cavity. The first piston disc and the second piston disc define the second cavity inside the body. The body has a first passageway in fluid communication with the first cavity, a second passageway, a third passageway located between the first and second passageways in the body axial direction. The first, second and third passageways communicate with each other in parallel by a main pipeline passage and a throttle opening, formed in the passageway portion of the main pipeline, which has a connection with the second and third passageway, and the second and third passageways are in fluid communication with hydraulic channel of the system.

EFFECT: increase of machine transmission control reliability.
