  • Patent number: 8042788
    Abstract: A thin disk portion, which extends radially, and a rib provided in an outer circumference part of the disk portion are formed in a valve body. A ring-like seal projection to be pressure-contacted with the disk portion to seal a valve is formed in a case. Because the disk portion is thin, deformation occurs along an end surface of a seal projection when the valve is sealed. Even when the seal projection is deformed due to fuel swelling or the like, sealing is enabled along the entire circumference thereof. High sealability is achieved even when the resin components are pressure-contacted with each other.

  • Patent number: 7926506
    Abstract: The fuel cutoff valve has a connection conduit that connects the connection hole to the approximately round shaped cross section tube passage. With the connection conduit, the connection hole and the flow path area are almost the same, and this comprises a curved passage part that makes the rising gas flow from the connection hole face in the horizontal direction, and a connection passage part that leads the gas flow from the curved passage part to the connection passage part. The fluid guide member that constitutes the curved passage part is a passage that has an inclined face that makes the rising gas flow that flows out from the connection hole face in the horizontal direction, and a passage upper surface formed from a flat surface continuous from the upper edge of the inclined face and arranged above the connection hole. The connection passage part is formed such that the cross section shape of the passage upper surface gradually faces the round shaped cross section of the tube passage.

  • Patent number: 7806135
    Abstract: A variable flow valve includes a housing, a valve element, an urging member, a first valve, a second valve, and a guide flow passage. The housing has an inlet opening, and an outlet opening. The first valve and second valve are formed between the valve element and the housing. The valve element has a separator wall. The separator wall separates the inlet opening and the outlet opening, and makes the second valve together with the housing. The guide flow passage is disposed on an inlet-opening side of the separator wall, and connects the inlet opening with the outlet opening when the separator wall moves to open the communication between the inlet opening and the outlet opening. The variable flow valve can make fluids flow without generating any turbulent flow, and can cope with the increment/decrement of required breather-gas flow volume more accurately.

  • Publication number: 20090000669
    Abstract: A fuel cutoff valve 10 has a float assembly 52 and an upper valve plug 60 located in a valve chest 30S defined by a casing 20. The float assembly 52 has a valve support member 55 formed in its upper portion to support the upper valve plug 60. The upper valve plug 60 has a support convex 66b held on a support plane 56a of the valve support member 55, where a center of gravity of the upper valve plug 60 is located below a supporting point 55a around which the support convex 66b is balanced on the valve support member 55. The upper valve plug 60 includes a first valve section 61 and a second valve section 65. The first valve section 61 has a first valve body 62 and a sheet member 64. The first valve body 62 is made of POM (polyoxymethylene), while the second valve section 65 is made of PA6 (polyamide) containing 30% of glass fibers. The second valve section 65 is accordingly structured to have a lower density than the first valve body 62.

  • Patent number: 7448364
    Abstract: In a fuel cutoff valve of the invention, an opening at a lower end of a cylindrical bottom member defines a full level of fuel. The opening of the cylindrical bottom member has a flange that is protruded in a horizontal direction. This structure of the invention effectively interferes with invasion of the air into a casing of the fuel cutoff valve in the course of fuel supply to the full level.

  • Patent number: 7428914
    Abstract: A flow control valve includes a housing, a valve element, a valve-element urger, a first valve, and a second valve. The first valve closes the communication between inlet and outlet openings of the housing gradually when the valve-element urger moves the valve element away from the inlet opening. The second valve opens the communication between the inlet and outlet openings when the valve-element urger moves the valve element away from the inlet opening. The first valve is opened, and the second valve is closed when a differential pressure between a pressure of the fluid on an inlet-opening side and a pressure of the fluid on an outlet-opening side is a predetermined value or less. The second valve opens the communication between the inlet and outlet openings instantaneously when the differential pressure is more than a predetermined value.
