摘要:
The invention relates to a pressure gauge (1) for arranging in a chamber of an internal combustion engine. Said pressure gauge (1) comprises a housing (3), a force transmission element (6) which projects out of the housing (3), and a pressure sensor (23) which is arranged inside the housing (3). The pressure sensor (23) is supported on a fixing element and is actively connected to the force transmission element (6) for detecting a pressure in the chamber. The pressure sensor (23) comprises a continuous recess (26) through which an electrical line (7) is guided. The pressure gauge is provided with a positioning element (20) comprising a continuous recess (31) in a guiding region (30), the electrical line (7) being guided through the continuous recess (31) and the positioning element (20) having a reduced thickness in the guiding region (30). In this way, friction of the electrical line (7) on the continuous recess (31) in the guiding region (30) can be reduced, thereby improving the pressure measurement.
摘要(中):
本发明涉及一种用于布置在内燃机的腔室中的压力计(1)。 所述压力计(1)包括壳体(3),从壳体(3)突出的力传递元件(6)以及布置在壳体(3)内部的压力传感器(23)。 压力传感器(23)支撑在固定元件上并且主动地连接到力传递元件(6)以检测腔室中的压力。 压力传感器(23)包括连续的凹槽(26),电线(7)通过凹槽(26)被引导。 压力计设置有定位元件(20),该定位元件包括位于引导区域(30)中的连续凹槽(31),电线(7)被引导穿过连续凹槽(31)并且定位元件(20) 在引导区域(30)中厚度减小。 以这种方式,电导线(7)在引导区域(30)中的连续凹部(31)上的摩擦可以减小,由此改善压力测量。
