Abstract: A hypodermic syringe includes a barrel with a plunger slidably extending therein. The plunger includes an outer plunger element and an inner plunger element telescoping together. A plunger cap may be advanced after injection to rotate the plunger. A resistance lock retains the cap and plunger indexed until actuation. The rotation actuates latches and locking fingers on the luer hub to engage a probe axially and rotationally on the seal end of the plunger and disengage the slots in the barrel, respectively. The rotation disengages the seal stop to release the annular seal and finally releases the engagement between the outer plunger element and inner plunger element. The foregoing provides for the retraction of the luer hub and associated needle into the barrel.

Abstract: A hypodermic syringe includes a barrel with a plunger slidably extending therein. The barrel may include a barrel adapter at one end to define a luer hub socket and the outer walls of slots in the barrel. The plunger includes an outer plunger element and an inner plunger element telescoping together with a bungee resisting extension of the assembly. The inner and outer plunger elements may be locked in the extended position with the bungee in tension. A seal stop is located at the seal end of the plunger to define an annular pinch therewith to hold an annular seal in radial extension sealing against the internal sidewall of the barrel. A luer hub is fixed at the needle end of the barrel. A plunger cap may be advanced after injection to rotate the plunger. A resistance lock retains the cap and plunger indexed until actuation.

Abstract: A hydraulic clutch actuator system having a vibration damper in the system including an elastomeric diaphragm and a steel diaphragm. One face of the elastomeric diaphragm is in communication with fluid in the system so that the diaphragm may deflect in response to low frequency system vibrations to effect damping of these vibrations. The steel diaphragm is positioned generally parallel to and proximate the other face of the elastomeric diaphragm so as to form a back-up for the elastomeric diaphragm so that the elastomeric diaphragm may deform against the steel diaphragm in response to high frequency system vibrations to cause deflection of the steel diaphragm to effect damping of the high frequency vibrations. An apertured stop structure above the elastomeric diaphragm functions to limit upward excursions of the elastomeric diaphragm and further functions to maintain communication between the chamber above the elastomeric diaphragm and the damper port to the system.

Abstract: A hydraulic clutch actuator system having a vibration damper provided in the system between a master cylinder and a slave cylinder of the system. The damper includes an elastomeric diaphragm and a spring steel diaphragm. One face of the elastomeric diaphragm is in fluid communication with hydraulic fluid in the system so that the elastomeric diaphragm may deflect in response to low frequency vibrations transmitted through hydraulic fluid in the system to effect damping of the low frequency vibrations. The spring steel diaphragm is positioned in the system generally parallel to and proximate the other face of the elastomeric diaphragm so as to form a back-up for the elastomeric diaphragm so that the elastomeric diaphragm may deform against the spring steel diaphragm in response to high frequency vibrations transmitted through the hydraulic fluid to cause deflection of the spring steel diaphragm to effect damping of the high frequency vibrations.
