COMPOSITE FASTENING DEVICE

摘要

In a vehicle having an internal combustion engine, it is usual to monitor the oil pressure of the engine's lubrication system to prevent damage to the engine in the event the oil pressure decreases to an unacceptable level. In this regard, a gauge or a warning light on the vehicle dashboard indicates when the oil pressure is low in response to a signal from an oil pressure transducer connected to the engine lubrication system. Herein is described an improved oil pressure transducer with a relatively easily crushable thin metal base housing member. The base housing portion is generally hollow andincludes a threaded male support portion adapted to be received in a threaded aperture of the engine and fluidly communicated with the lubrication system. The base includes a molded wrenching portion of elastomeric material formed about the housing for contact by an installation tool. The molded wrenching portion is shaped on its outer circum-ference so as to facilitate rotation of the transducer by tool means without damage to the thin metal wall thereof.
