摘要： A pressure sensor portion having a pressure-responsive element for detecting gas pressure in reference to the atmospheric pressure is connected to a mounting body such as a canister mounted on a vehicle by means of a fragile connecting member. The connecting member breaks off to dismount the sensor device from the mounting body when a high impact due to an accidental collision or crash is imposed on the sensor device, and thereby an inlet port connected to the sensor portion for introducing gas pressure thereinto is prevented from being broken or damaged by such a collision impact. The fragile connecting member may include a tubular pipe formed integrally with a cover that hermetically closes an inner cavity of the sensor portion. A mounting bracket connected to the sensor portion via the fragile connecting member may be used to mount the sensor device on the mounting body.

摘要： A fuel vapor treating apparatus that collects fuel vapor produced in a fuel tank and treats the vapor without releasing it into the atmosphere. The treating apparatus is provided with a canister that collects the fuel vapor through a vapor line. A vapor control valve provided in the canister adjusts the flow of fuel vapor directed toward the canister from the tank. A purge line connects the canister to an air intake passage of an engine. The fuel collected in the canister is purged into the air intake passage through the purge line. A purge control valve provided in the purge line adjusts the flow rate of the fuel flowing through the purge line. A three-way valve selectively switches the section to which the pressure sensor is connected between the tank side and the canister side. An electronic control unit (ECU) controls the second control valve and the three-way valve. The ECU tests the sealing of the tank side and the canister side based on the tank pressure and the canister pressure, which are detected by the pressure sensor. The ECU controls the three-way valve to alternately connect the pressure sensor to the tank side and the canister side during a predetermined time period subsequent to the starting of the engine. As the connection is switched, alteration in the output occurs in accordance with the normal state or abnormal state of the connected side. The ECU further tests the pressure sensor by distinguishing the output alteration.
摘要翻译：一种燃料蒸汽处理装置，其收集在燃料箱中产生的燃料蒸气并处理蒸气而不将其释放到大气中。处理装置设置有通过蒸汽管线收集燃料蒸气的罐。设置在罐中的蒸汽控制阀调节从罐引导朝向罐的燃料蒸汽的流动。吹扫线将罐连接到发动机的进气通道。收集在罐中的燃料通过净化管线被净化到进气通道中。设置在净化管线中的清洗控制阀调节流过净化管线的燃料的流量。三通阀选择性地切换在罐侧和罐侧之间连接有压力传感器的部分。电子控制单元（ECU）控制第二控制阀和三通阀。 ECU根据由压力传感器检测到的油箱压力和油罐压力来测试罐侧和罐侧的密封。在发动机起动之后的预定时间段内，ECU控制三通阀以将压力传感器交替地连接到罐侧和罐侧。当连接被切换时，根据连接侧的正常状态或异常状态发生输出变化。 ECU通过区分输出变化来进一步测试压力传感器。
