(54) ГИДРОРАСПРЕДЕЛИТЕЛЬ МЕХАНИЗИРОВАННОЙ КРЕПИ Стакан удерживаетс  от проворота относитель но корпуса штцфтом 17. На седле корпуса выполнен паз 18, гидравлически сообщающий канал слива с полостью стакана. Паз необходим в том случае, когда распределительна  втулка будет ошибоч но оставлена над каналом слива и герметично закроет ето, тогда жидкость не сможет выйти из рабочих полостей цили1щров секции крепи (на чертеже не показаны). При работе поворотом руко тки 14 золотник 5 устанавливаетс  в необходимое рабочее положение. Рои нажатии на руко тку 14 последн  , взаимодейству  с толкателем 16, открывает отсечной клапан 15, вследствие чего рабоча  жидкость попадает в полость цент ральной втулки .7 .и затем через распределительную втулку 6 - в рабочую полость иипиндров секции крепи. При сн тии усили  с руко тки толкатель 16 возвращаетс  в исходное положение и отсечной клапан 15 закрываетс , прекраща  проход жидкости к рабочим полост м цилиндров крепи. Милые габариты, простота в изготовлении и эксплуатации обеспечивают эффективное применение предлагаемых распределителей рабочей жидкости. Формула изобретени  Гидрораспределитель механизированной крепи , включающий корпус с каналом слива и седлом, и стакан, в полости которого устано лен золотник с распределительной втулкой, отличающ ийс  тем, что, с целью уменьшени  габаритов конструкции, канал слива расположен соосно распределительной втулке , а в седле выполнен паз дл  сообщени  канала слива с .полостью стакана. Источники информации, прин тые во внимание при экспертизе: 1.Авторское свидетельство ССХИР № 507701, кл. Е 21 D 23/16, 1974. (54) HYDRODISTRIBUTOR MECHANIZED FASTENER The glass is kept from turning around the body with a pin 17. A slot 18 is made on the body seat, hydraulically connecting the drain channel to the cup cavity. The groove is necessary in the case when the distribution sleeve is mistakenly left above the drain channel and hermetically closed, then the liquid will not be able to exit the working cavities of the cylinder of the support section (not shown). When operating by turning the knob 14, the spool 5 is set to the desired operating position. The swarm pressed the handle 14 last, interacting with the pusher 16, opens the shut-off valve 15, as a result of which the working fluid enters the cavity of the central sleeve .7. And then through the distribution sleeve 6 - into the working cavity of the supports of the support section. When the force is removed from the handle, the pusher 16 returns to its original position and the shut-off valve 15 closes, stopping the passage of fluid to the working cavities of the support cylinders. Cute dimensions, ease of manufacture and operation ensure the effective use of the proposed distributors of working fluid. Claims of the invention A mechanized hydraulics distributor comprising a body with a drain and a seat and a cup in which a spool with a distribution sleeve is installed, which is designed to reduce the size of the structure, and the drain is arranged in the saddle. a groove for communicating the discharge channel with the cup cavity.
