Abstract

1. Поршень (12) насоса, совершающий возвратно-поступательное движение в цилиндре (4) насоса, при этом между поршнем (12) насоса и цилиндром (4) насоса имеется кольцеобразная полость (26), которая определена первым уплотнением (20) и вторым уплотнением (24) и в которой создается давление, причем первое уплотнение (20) и второе уплотнение (24) расположены на одном и том же элементе, образующем поршень (12) насоса, отличающийся тем, что он содержит уравновешивающий поршень (30), выполненный с возможностью перемещения в уравновешивающем цилиндре (28) в поршне (12) насоса, причем уравновешивающий поршень (30) сообщается своим первым торцом с рабочим торцом (22) поршня (12) насоса, а вторым торцом - с кольцеобразной полостью (26) через канал (34) в поршне.2. Поршень по п.1, отличающийся тем, что кольцеобразная полость (26) снабжается находящейся под давлением текучей средой через обратный клапан (44) и канал (46) в цилиндре.1. A piston (12) of the pump reciprocating in the cylinder (4) of the pump, while between the piston (12) of the pump and the cylinder (4) of the pump there is an annular cavity (26), which is defined by the first seal (20) and the second seal (24) and in which pressure is created, the first seal (20) and the second seal (24) are located on the same element forming the piston (12) of the pump, characterized in that it contains a balancing piston (30), made with the possibility of movement in the balancing cylinder (28) in the piston (12) on a sucker, and the balancing piston (30) communicates with its first end face with the working end face (22) of the pump piston (12), and the second end face with the annular cavity (26) through the channel (34) in the piston. 2. A piston according to claim 1, characterized in that the annular cavity (26) is supplied with pressurized fluid through a check valve (44) and a channel (46) in the cylinder.
