20110168931 | SOLENOID VALVES CAPABLE OF CONTROLLING VALVE-OPENING AREA - A solenoid valve has a valve housing, first and second valve members, first and second biasing members, a pressing rod and an electromagnetic driving member. The valve housing defines a fluid pathway for flowing fluid therein. The first and the second valve members are configured to open and close the fluid pathway, respectively. The first biasing member biases the first valve member in a direction for closing the fluid pathway. The second biasing member biases the second valve member in a direction for closing the fluid pathway. The electromagnetic driving member sequentially presses the pressing rod against the first valve member and the second valve member in order to open the fluid pathway in stages. | 07-14-2011 |
20110197861 | CANISTER DEVICES FOR GAS VEHICLE - A canister for a fuel vapor processor connected to a fuel tank and an engine includes a housing defining an adsorption chamber therein and an absorber being capable of adsorbing fuel vapor and filled in the adsorption chamber. The housing has an air communicating pipe communicating the adsorption chamber with the atmosphere, an introducing pipe communicating the adsorption chamber with the fuel tank and an exhaust pipe communicating the adsorption chamber with the engine. It is configured that airflow resistance in the canister along a first route between the air communicating pipe and the exhaust pipe is smaller than airflow resistance along a second route between the introducing pipe and the exhaust pipe. | 08-18-2011 |
20110214572 | CANISTERS - A canister includes a first fuel vapor adsorption device and a second fuel vapor adsorption device. The second fuel vapor adsorption device can adsorb a part of fuel vapor that still remains in a gas after desorption by the first fuel vapor adsorption device. The second fuel vapor adsorption device includes a first passage containing a fuel vapor adsorption material and a second passage containing no fuel vapor adsorption material. The first passage and the second passage allow the gas to flow therethrough. A gas introduction device allows the fuel vapor to flow from the second passage into the first passage. | 09-08-2011 |
20110240490 | CANISTERS - A canister for trapping a fuel vapor vaporized in a fuel tank has a casing defining an adsorption chamber therein, an adsorbent capable of adsorbing the fuel vapor and filled in the adsorption chamber and a flow regulation plate disposed in the casing. The casing has a fuel introducing port configured to introduce the fuel vapor from the fuel tank into the adsorption chamber, and an air communicating port communicating the adsorption chamber with the atmosphere. The air communicating port is formed on a side surface of the casing extending in a direction of gravitational force. The flow regulation plate disposed at an end of the adsorption chamber near the air communicating port and has an opening configured to communicate the adsorption chamber with the air communicating port. The opening is positioned above the air communicating port in the direction of gravitational force. | 10-06-2011 |
20110296997 | VALVES CAPABLE OF CONTROLLING VALVE-OPENING AREA - A valve includes a valve housing defining therein a fluid passage composed of a first passage and a second passage, a first valve member configured to open and close the fluid passage, a first biasing member pressing the first valve member in a first valve-closing direction along a flow direction from the first passage to the second passage, a second valve member configured to open and close the fluid passage, a second biasing member pressing the second valve member in a second valve-closing direction along the flow direction from the first passage to the second passage, an electromagnetic driving member having an pressing member opening the first valve member and the second valve member in stages, a third valve member configured to open and close the fluid passage, and a third biasing member pressing the third valve member in a third valve-closing direction along a flow direction from the second passage to the first passage. The third valve member is configured to open the fluid passage when internal pressure of the first passage is higher than internal pressure of the second passage by a predetermined value. | 12-08-2011 |
20120006504 | SHAPED HEAT STORAGE MATERIALS - A shaped heat storage material has a shaped body composed of a binder and heat storage capsules containing a heat storage material therein. And, the shaped body has at least one of a projection, a depressed portion and a hollow structure defining a hollow space therein. | 01-12-2012 |
20120012474 | SHAPED HEAT STORAGE MATERIALS INCLUDING HEAT TRANSFER MEMBERS - A shaped heat storage material has a shaped body composed of a binder and heat storage capsules containing a heat storage material therein. And, the shaped body has at least one of a projection, a depressed portion and a hollow structure defining a hollow space therein. | 01-19-2012 |
20120186563 | CANISTERS - A canister has a canister case, an adsorbent chamber defined in the canister case, and an adsorbent disposed in the adsorbent chamber. The adsorbent can adsorb fuel vapor as the fuel vapor flows through the adsorbent chamber in a first direction. On the other hand, the adsorbent allows desorption of fuel vapor as air flows through the adsorbent in a second direction opposite to the first direction. The adsorbent chamber includes a first adsorbent chamber and a second absorbent chamber communicating with each other. The first adsorbent chamber is disposed on an upstream side of the second adsorbent chamber with respect to the first direction. The adsorbent includes a first adsorbent disposed in the first adsorbent chamber and a second adsorbent disposed in the second adsorbent chamber. A desorption promoting device is disposed in the second adsorbent chamber and can promote desorption of fuel vapor from the second adsorbent. | 07-26-2012 |
