Abstract: Изобретение относится к области машиностроения и может быть использовано для уплотнения поршней двигателей внутреннего сгорания и прочих механизмов. К техническому результату относится улучшение компрессии газов в цилиндре ДВС при сохранении герметичности уплотнения на весь срок службы колец за счет использования дополнительного разрезного кольца с прямоугольной выемкой по всей цилиндрической окружной поверхности, в которую плотно входит основное разрезное поршневое кольцо, и расположения на основном и дополнительном разрезных поршневых кольцах разрезов, разнесенных относительно друг друга на 180°. Кроме того выполнение колец предложенным образом упрощает технологию изготовления колец без изменения их срока эксплуатации. Достижение данного технического результата обеспечивается тем, что поршневое компрессионное кольцо двигателя внутреннего сгорания содержит установленные в канавке поршня основное разрезное поршневое кольцо, а также дополнительное разрезное кольцо, расположенное в пространстве концентрично с поршневым кольцом и контактирующее своей внутренней цилиндрической окружной поверхностью с цилиндрической поверхностью дна поршневой канавки, при этом дополнительное разрезное кольцо снабжено пазом, выполненным на его поверхности. Причем паз на дополнительном разрезном кольце выполнен в виде прямоугольной выемки, расположенной по всей цилиндрической окружной поверхности. Основное разрезное поршневое кольцо плотно вставляют в выемку. При этом положение разрезов на основном и дополнительном разрезных кольцах устанавливают разнесенными относительно друг друга на 180°, что способствует обеспечению полной герметичности уплотнения. 2 ил.

Abstract: FIELD: measurement. 
     SUBSTANCE: invention relates to measurement equipment, in particular, to linear speed meters operating on the basis of accelerometers measurements, and can be used for measurement of linear speed of ground vehicles. On vehicle wheel (9) are uniformly located along circle of preset radius with axes of sensitivity oriented perpendicular to axis of wheel rotation, and accelerometers (1–8) are rigidly fixed. Diametrically located accelerometers are connected to corresponding inputs of adders (10–13). Sum of signals excluding effect of gravity acceleration is generated at summator output (10–13). Obtained sums are transmitted to the inputs of analogue-to-code converters (14–17) and further through input ports (18–21) to microcontroller (22). Taking into account formation of microcontroller (23) polling at each step k, speed is determined by formula  
           , 
     where  R  is wheel radius of vehicle;  r  is preset radius of installation of accelerometers on wheel;  a     i    (k) is the acceleration measured by the  i     th    accelerometer at the  k     th    step of the microcontroller;  n  is even number of accelerometers. Output port (23) of microcontroller (22) is connected to the input of the wireless data transmission device (24), which is the output of the wheel speed sensor of the vehicle.
