Claim 1
Independent Claim 155 words
In a measuring head apparatus for the inspection of machine parts which includes a sensing assembly having a probe for engaging a workpiece to be measured by moving relative thereto, a base, a parallelogram assembly including a leaf spring system which is supported by the base, and a plurality of support members coupled to the spring system, said support members supporting the sensing assembly therefrom, the improvement comprising fluidic damping means which includes a reservoir supported by the base means, a restrictor supported by the parallelogram assembly support members and which has a portion thereof which extends into the reservoir and moves therein as a paddle with the motion of the parallelogram assembly and the probe, said reservoir containing fluid and said restrictor extending below the level of said fluid, and adjustable means coupling the restrictor to said parallelogram assembly to adjust the extent to which the restrictor extends into the fluid in the reservoir.
