Уплотпительпые элементы 14 и 15 могут быть изготовл;екы из эластомеров,  а их торцовой поверхности выполнены два концентрично расположенных кольцевых выступа 20 и 21, причем наружный выступ 21 меньше по высоте внутреннего выступа 20, на котором выполнена радиальна  канавка 22, образующа  с поверхностью 16 седла 18 канал 23.modestry closed heat no. Their elastic sealing elements 14 and 15 with the surfaces 16 and 17 of the saddles 18 and / I made in the housing cavities. The sealing elements 14 and 15 can be made of elastomers, and their end surfaces are made of two concentrically arranged annular protrusions 20 and 21, the outer protrusion 21 being smaller in height than the internal protrusion 20, on which the radial groove 22 is formed, forming with the surface 16 of the saddle 18 channel 23.

Предохранительный клапан функционирует следуюилим образом.The safety valve functions in the following manner.

При работающем компрессоре обе полости 2 и 3 заполн ютс  через входной патрубок и регул тор давлони . Предположим, что контур, подсоединенный справа к клапану , отрегулирован на большее давление, чем контур, подсоеднненный слева.With the compressor running, both cavities 2 and 3 are filled through the inlet and pressure regulator. Suppose that the circuit connected to the right of the valve is adjusted to a greater pressure than the circuit connected to the left.

Рабочее давленне через кланаи 23 воздействует на ограниченную внешним кольцевым выступом 21 большую эффективную поверхность запорных элементов 12 и 13. При достижении давлени  отпирани  запорный элемент 12 поднимаетс , внешний кольцевой вьютуп 21 отрываетс  от поверхности 16, уиругпе кольцевые выступы 21 и 20 начинают восстанавливать свою форму, при этом внутренний выступ 20 еще контактирует с поверхностью 16. Воздух перетекает из полости 2 через канал 23 в ресивер . Воздух действует по меньшей эффективной поверхности, ограниченной внутренним кольцевым вьютупом 20.The working pressure through the clan 23 acts on the large effective surface of the locking elements 12 and 13, which is limited by the outer annular protrusion 21. while the inner protrusion 20 is still in contact with the surface 16. Air flows from the cavity 2 through the channel 23 into the receiver. The air acts on a less effective surface bounded by an internal annular vyupup 20.

Вследствие этого давление в полост х 2 и 3 увеличнваетс . Приращени  давлени , завис щего от сооТ|НОШе;нй  обеих эффективиых поверхностей, достаточно дл  компенсации неточности в регулировке величины давлени , при которой начинаетс  заполнение ресиверов контуров. При этом воздух перетекает из полости 3 в полостьAs a consequence, the pressure in cavity 2 and 3 increases. The increments of pressure, depending on the cooT | NASH; of both effective surfaces, are sufficient to compensate for the inaccuracy in adjusting the pressure at which the receivers of the circuits begin to fill. When this air flows from the cavity 3 into the cavity

По мере заполнени  ресиверов давление в полост х5 through the channel between surface 17 and element 15 into the receiver, and the locking element 12 begins to move upwards. As the receivers fill the cavity pressure
