A method that includes coupling an external, removable fuel pressurization system to a fuel system of a vehicle. The fuel system of the vehicle is pressurized with the fuel pressurization system while the vehicle is parked and without activating a fuel consumer (e.g., an engine) of the vehicle. Decay of pressure of the fuel system is monitored following pressurization of the fuel system, and one or more of a leak, or a replaceable component, of the fuel system of the vehicle is detected based on at least in part on the decay of pressure that are monitored.

A leak detection device operable to measure fluid leaks in an element to be tested that is positioned in a first enclosure. In one example, a measuring module is positioned in a second enclosure and connected to the first enclosure and the element to be tested by an aeraulic connection. At least one of the first enclosure and the measuring module are thermally insulated using an insulating material.

A sealing assembly for sealing an electrical component having an opening includes a cover coupled with the electrical component and a plug assembly fixed to the cover. The cover has a through-hole for injecting air during leakage tests of the electrical component and a plurality of engaging elements. The plug assembly has a single wire seal sealing the through-hole and a plurality of locking elements reversibly engaging the engaging elements. The cover seals the opening of the electrical component in an air-tight manner when the plug assembly is inserted into the through-hole.

The invention relates to an adapter part (9) for connecting a medical hollow body (11) to a tension/compression measuring device (3), comprising a first connecting end (13), which is designed to connect the adapter part (9) to an interior (15) of a medical hollow body (11) in a fluid-tight manner, and comprising a second connecting end (17), which has a pressure chamber (19) and is designed to operatively connect the adapter part (9) to a tension/compression measuring device (3), so that a pressure in the pressure chamber (19) can be adjusted by means of the tension/compression measuring device (3), a hollow channel (21) passing through the adapter part (9) from the pressure chamber (19) to the first connecting end (13).

The present invention relates to leakage detection unit (100) comprise of an upper housing (5), a lower housing (6) accommodating an electromechanical valve (1), a pump assembly (2), a pressure sensor (3) and a bush (4), wherein the pump assembly (2) includes a pump that permits flow of air that, due to which pressure in passage of the pump becomes constant after a time interval and that pressure is considered as reference pressure. The pressure is measured by help of the pressure sensor (3) and in case the measured pressure is not equal or above to the reference pressure than there is leakage in the isolation valve (100), whereas in case the measured pressure is equal or above the reference pressure that there is no leakage or some permissible amount of leakage in the fuel tank within the time interval.

An apparatus includes an enclosure designed to house electronics and a ventilation plug fastened to an exterior of the enclosure, the ventilation plug being adapted for field testing hermeticity.

The single rod ultrasonic leak detection tool will be used to detect leaking fuel rods by evaluation if there is water inside the rod. The test will be performed by moving one fuel rod between two ultrasonic transducer oriented in a pitch/catch configuration. The detection tool uses ultrasonic transducers as the primary method to detect leaking fuel rods. Two probes are preferably positioned near the fuel rod in a pitch/catch or transmitting/receiving configuration. One probe 36 sends the signal into the rod and the other probe of a set of probes receives the signal. An evaluation of the received signal is performed in various embodiments, to determine leak tightness of the fuel rod. In various aspects, two sets of probes may be utilized so that measurements can be taken on both sides of the fuel rod.

The present invention is a bleeding air regulator control pneumatic circuit for supplying air to a leakage detection system for testing a device under test for leakage. The bleeding air regulator control pneumatic circuit includes an air supply source having an outlet port for supplying compressed air to the leakage detection system; an air relay having a first port in fluid communication with the outlet port of the air supply source and a second port in fluid communication with an inlet of the leakage detection system; a pressure regulator having an inlet port in fluid communication with and connected at a point between the outlet port of the air supply source and the first port of the air relay, and an outlet port in fluid communication with and connected to a third port of the air relay; a bleed valve having a first port in fluid communication with a fourth port of the air relay and a second bleed port; and a flow control valve positioned between and in fluid communication with the air relay and the bleed valve.
