    Abstract: Provided is a micro-valve having a laminate structure capable of improving sealing performance when a foreign substance is mixed. The micro-valve 10 has a laminate structure and includes a base layer 20 and a diaphragm layer 30. The base layer is formed with an inlet port 23 for introducing a gas into the micro-valve and an outlet port for allowing the gas to flow outside. The diaphragm layer is arranged to face the base layer. The diaphragm layer switches the flowing and blocking of the gas from the inlet port to the outlet port by elastic deformation thereof. The diaphragm layer has a configuration in which a plurality of deformation regions 33 and a plurality of rigid body regions 34 are alternately formed, the deformation region being elastically deformable in accordance with an inflow of a pneumatic fluid into the micro-valve. The diaphragm layer closes at least one of the inlet port and the outlet port by elastic deformation of at least a part of the plurality of deformation regions.

  • Patent number: 10837409
    Abstract: A purge system malfunction diagnosis device is configured to diagnose a malfunction in a purge system mounted on a vehicle. The purge system includes a canister, a purge passage, a purge valve capable of opening and closing the purge passage, an outside air passage configured to cause the canister to communicate with an outside air opening, an outside air valve capable of opening and closing the outside air passage, and a system pressure sensor configured to detect a pressure in the purge system. In a state where the outside air passage is closed, a diagnosis mode is executed on a basis of a relationship between the pressure in the purge system and an integrated value of flow rate estimates of a purge gas. In the diagnosis mode, a parameter to be used for diagnosing a malfunction in the purge system is adjusted in a case where the flow rate estimate is lower than a flow rate threshold.
