A composite tube transducer cylinder is manufactured from molded material in which embedded strips of resistive and conductive material are exposed to the inside surface and wherein a piston operating within the cylinder may make contact between a conductive and a resistive strip as a means for determining piston position.

Composite tube transducer cylinder

A fluid cylinder comprising a tube having a sidewall and at least one open end, the sidewall has a locking groove formed therein adjacent each of the at least one open ends, each of the open ends includes an edge which includes a chamfer. The fluid cylinder also includes at least one endcap for closing the at least one open end, each of the at least one endcaps comprising: a leading end having a groove formed therein, said groove adapted to receive a compressible retaining ring, the retaining ring adapted to engage the locking groove when the at least one open end is closed by the at least one endcap. Each of the endcaps also includes a shoulder and a sealing member located between the leading end and the shoulder, the sealing member is adapted to sealingly engage the edge of the at least one open end. The sealing member includes a base and a lip made integral with the base, the lip including along one side, said chamfer adapted to engage the chamfered tube edge, said lip adapted to be movable between a first position where the lip is substantially parallel to the shoulder and a second position where the lip is in abutment with the shoulder.
