摘要： A fluid volume measuring apparatus for measuring volume of fluid flowing out of a measured object includes a passage member that defines a measurement passage. The measurement passage is filled with fluid, which is capable of moving in the measurement passage in accordance with volume of fluid flowing out of the measured object. The fluid filled in the measurement passage forms a bubble. The passage member has a translucent portion in a predetermined measurement range, in which the bubble displaces in accordance with volume of fluid flowing out of the object to be measured. The translucent portion is formed of a translucent material. Volume of fluid, which flows out of the measured object, is measured in accordance with displacement of the bubble.

摘要： A diaphragm is uniformly and finely deformed by compressed air supplied from an electro-pneumatic regulator, so that test fluid is supplied in conformity with the deformation of the diaphragm. In this way, a flow quantity of the test fluid supplied from a fluid supply device to a measurement passage is accurately adjusted. Therefore, an accuracy of a flow accuracy check device is improved, and a leakage measurement accuracy at the time of measuring a leakage from a fuel injection valve with a flow measurement apparatus is improved. At the time of measuring the leakage from the fuel injection valve, the diaphragm is stopped at a balanced position where a force of the air supplied from the regulator and a resilient force of the diaphragm is balanced. Therefore, a change in a volume of the measurement passage, which would be otherwise caused by movement of the diaphragm, does not occur.
摘要翻译：通过从电动气动调节器供给的压缩空气使膜片均匀且微细地变形，从而根据隔膜的变形供给试验液。以这种方式，精确地调节从流体供应装置供给到测量通道的测试流体的流量。因此，提高了流量精度检查装置的精度，并且提高了使用流量测量装置测量来自燃料喷射阀的泄漏时的泄漏测量精度。在测量来自燃料喷射阀的泄漏时，隔膜停止在从调节器供应的空气的力和隔膜的弹性力平衡的平衡位置处。因此，不会发生由隔膜的移动引起的测量通道的体积变化。

摘要： A liquid measurement apparatus is configured to measure an amount of liquid flowing from a measured object. The apparatus includes a passage member having a measurement passage being connected to the measured object at one end. The measurement passage is filled with liquid. The apparatus further includes a closed vessel, which is connected to an other end of the measurement passage and filled with saturated vapor of the liquid. The apparatus further includes an analyzer. The liquid filled in the measurement passage contains a bubble, which is movable in accordance with change in amount of the liquid in the measurement passage. The analyzer is configured to calculate a travel distance of the bubble and configured to measure the amount of the liquid flowing from the measured object based on the calculated travel distance.
