Description

Изобретение касаетс  уплотнительного устройства, выполненного в виде деформируемой втулки, установленной между поршнем и.цилиндром и нагружаемой с внешней поверхности давлением жидкости .The invention relates to a sealing device, made in the form of a deformable sleeve, installed between the piston and the cylinder and the fluid pressure loaded from the outer surface.

В известных устройствах аналогичного назначени , вследствие неодинаковых законов распределени  давлени  по образующим втулки с внешней и внутренней стороны происходит неравномерна  деформаци  ее, в результате зазор между втулкой и поршнем принимает клинообразную форму, что приводит к повышенному расходу жидкости.In known devices of similar purpose, due to unequal pressure distribution laws forming the bushings from the outside and inside, uneven deformation occurs, resulting in a wedge-shaped gap between the sleeve and the piston, which leads to increased fluid flow.

Особенность предлагаемого устройства состоит в том, что зазор вокруг втулки выполнен открытым с одной стороны дл  обеспечени  протока уравновешиваюшей жидкости и распределени  давлени  по образующим втулки как с внешней, так и с внутренней стороны.A feature of the proposed device is that the gap around the sleeve is made open on one side to provide a flow of balancing liquid and distribute pressure along the forming sleeve from both the outer and inner sides.

На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.

Устройство состоит из поршн  /, деформируемой втулки 2 и ци .1индра 3. Жидкость, давление которой измен ют, подводитс  по каналу 4 под поршень 1, откуда она протекает через кольцевой зазор поршнем и втулкой 2.The device consists of a piston /, a deformable sleeve 2 and qi. 1 of the cylinder 3. Liquid, whose pressure is changed, is supplied through channel 4 under the piston 1, from where it flows through the annular gap with the piston and sleeve 2.

Уравновешивающа  жидкость подводитс  от отдельного источника по каналу 5 и протекает через кольцевой зазор открытый с верхней стороны, в св зи с чем распределение давлений но образующим втулки как с внешней, так и с внутренней стороны происходит по одно . и тому же закону.The balancing fluid is supplied from a separate source through channel 5 and flows through the annular gap open from the upper side, and therefore the distribution of pressures but forming the sleeves from both the outer and inner sides occurs one at a time. same law.
