DEFINITION
Classification: 188/289
(under subclass 284) Device wherein a thrust member has an opening therein for passage of fluid therethrough, which opening is closed to a greater or lesser degree by an elongated bar, the length dimension of which bar reaches through said opening and the size of which bar; in dimension perpendicular to its length dimension, changes along the length of the bar.
(1) Note. In this subclass fluid moved by the piston flows through an orifice in the piston, the area of which orifice varies by reason of taper, or a groove, in the rod that extends through the orifice; thus the degree of fluid flow is dependent upon the position of the piston relative to the rod.
