.~.~.~ Having metering pin for varying spring rate
DEFINITION
Classification: 267/64.22
Having metering pin for varying spring rate:
(under subclass 64.15) A device including an orifice through which fluid flows, and a rodlike element which projects into the orifice to define a flow passage therebetween, wherein the rodlike element is adapted to reciprocate relative to the orifice, thus varying the size of the passage and variably regulating the flow therethrough to change either the rate of reflection or the rate of return of the device.
(1) Note. Devices in this subclass require that either the
reciprocating rodlike element or the orifice be of varying diameter to regulate the flow.
