    摘要: Hydraulic pressure transducer having an operating cylinder (10) with an operating piston (12) and operating piston rod (14) adapted for rapid traverse, and a transducer piston (22) and piston rod (24) guided within an axially connected power cylinder (20). The transducer piston rod (24) is of a smaller diameter than the operating piston rod (14) and is capable of plunging into the operating cylinder volume (16), the transducer piston rod (24) extending through a seal (58) separating said operating cylinder volume (16) from the power cylinder. In order to avoid repeated overtravel of the high pressure seal separating the traverse fluid inlet from the high pressure volume, a control sleeve (36) is guided on the piston rod (24) of the power cylinder, the control sleeve having a collar (38) near its front end, which is biased towards a stationary plane sealing surface (62) facing the operating cylinder (10) such that during the traverse stroke the control sleeve (36) is removed from the stationary plane sealing surface (42) and thus providing unobstructed admission for traverse stroke pressure fluid to the operating cylinder volume.
