(under subclass 388) Device wherein the force-responsive element (solid or fluid) has the characteristics of a spring
or its equivalent throughout the expected range of forces applied thereto during normal operation of the machine.
(1) Note. The presence of a relief valve in a fluid-pressure drive means indicates that the drive exhibits the characteristic of yield ability under certain conditions, hence is not wholly "resilient" (see (1) Note under subclass 390 and (1) Note under subclass 387).
