Flow limiter

A flow limiter for only hydraulic fluid, comprising at least one passage of reduced cross-section for the hydraulic fluid and formed only between two nonresilient contiguous pieces each having at least one planar face, one of the pieces comprising a recessed impression on the respective planar face, the passage of reduced cross-section defined between the recessed impression formed on the respective planar face and the planar face of the other piece, the length of the passage of reduced cross-section being adjusted by varying the relative positions of the two contiguous pieces, a hole located in one piece at one end of the passage of reduced cross-section and a hole located in the other piece at the other end of the passage of reduced cross-section, and recesses located along the recessed impression formed on the respective planar face in order to obtain between two adjacent recesses a passage of reduced cross-section of a precisely determined length such that a slight variation in the relative positions of the two contiguous pieces has no effect on said precisely determined length, and varying the positions of the pieces relative to one another effecting serially an alignment of the hole located in the other piece with the recesses.
