Patent number: 8038027Abstract: The fuel cap includes an outer cap as an outer envelope, an inner cap removably fitted in the outer cap through an opening therein, a canister located in a space between the outer cap and the inner cap for adsorbing a vaporized fuel. The fuel cap closes a fuel filler port for feeding a fuel to a fuel tank. The canister adsorbs a vaporized fuel vaporized from the fuel in the fuel tank. At least one of the outer cap and the inner cap defines a communication hole communicating with the space and an exterior. The canister includes a housing; and an adsorbent accommodated therein. The housing defines, on an end surface directed to the inner cap, an inlet for vaporized fuel and on another end surface directed to the outer cap, an outlet for gas.Type: GrantFiled: November 14, 2007Date of Patent: October 18, 2011Assignee: Toyo Roki Seizo Kabushiki KaishaInventors: Hiroyasu Ohsawa, Takashi Sakagami

Patent number: 7584931Abstract: A case holding mechanism includes a holding member and a member to be held thereby, one being mounted to the case and another to a body to which the case is to be held. The member to be held includes a first pair of parallel guide portions and another pair of parallel guide portions perpendicular to the one paired guide portions. The holding member disposed to be movable with respect to the guide portions therealong in a state restricted in thickness direction of the guide portions and adapted to hold the member to be held. The holding member includes a pair of slide portions slidable along outer surfaces of one paired guide portions, a lock portion extending between the paired slide portions in parallel with the one paired guide portions and engaged with the other paired guide portions, and a base portion connecting the slide portions and the lock portion.Type: GrantFiled: April 5, 2006Date of Patent: September 8, 2009Assignee: Toyo Roki Seizo Kabushiki KaishaInventors: Hiroyasu Ohsawa, Kazuya Matsuura, Takashi Sakagami, Kouichi Ikuma

The canister adsorbs a vaporized fuel vaporized from the fuel in the fuel tank. At least one of the outer cap and the inner cap defines a communication hole communicating with the space and an exterior. The canister includes a housing; and an adsorbent accommodated in the housing. The housing defines, on an end surface directed to the inner cap, an inlet for a vaporized fuel to flow into the inlet. The housing defines, on another end surface directed to the outer cap, an outlet for a gas, from which the vaporized fuel has been absorbed, to flow out of the outlet.Type: ApplicationFiled: November 14, 2007Publication date: May 15, 2008Applicant: TOYO ROKI SEIZO KABUSHIKI KAISHAInventors: Hiroyasu OHSAWA, Takashi SAKAGAMI

Patent number: 7175698Abstract: In a canister, an activated charcoal layer is placed in a fluid passage by which an air intake port is connected to a charge port or purge port, and a chamber dividing the charcoal layer into sections so as to traverse the fuel passage is defined by a grid and a filter pad placed on the surface of the grid. The grid has apertures uniformly formed on the surface of the grid contacting with the filter pad, so as to communicate with the chamber. Formation of the apertures on the surface of the grid prevents the filter pad from coming into the mesh of the grid, thus maintaining flatness of the filter pad.Type: GrantFiled: June 29, 2004Date of Patent: February 13, 2007Assignee: Toyo Roki Seizo Kabushiki KaishaInventors: Kazuya Matsuura, Takashi Sakagami, Kazuhiro Yamaguchi

Patent number: 7137293Abstract: A canister has: a canister body including an adsorbent case which is provided with an adsorption chamber filled with an adsorbent and a fuel steam introduction port, a purge port and an air communication port which are communicated with the adsorption chamber; and a filter body. The canister body and the filter body are communicated with each other through a communication passage, in which a leak detection valve is disposed to be detachable through an end opening formed to the communication passage.Type: GrantFiled: September 28, 2004Date of Patent: November 21, 2006Assignee: Toyo Roki Seizo Kabushiki KaishaInventors: Takashi Sakagami, Kazuya Matsuura

Publication number: 20050039603Abstract: There is prevented reduction in volume of a chamber, by which an activated charcoal layer for a canister is divided into sections. [MEANS TO SOLVE THE SUBJECT] In a canister, an activated charcoal layer is placed in a fluid passage by which an air intake port is connected to a charge port or purge port, and a chamber dividing the charcoal layer into sections so as to traverse the fuel passage is defined by a grid and a filter pad placed on the surface of the grid. The grid has apertures uniformly formed on the surface of the grid contacting with the filter pad, so as to communicate with the chamber. Formation of the apertures on the surface of the grid prevents the filter pad from coming into the mesh of the grid, thus maintaining flatness of the filter pad. The original volume of the chamber can be maintained, so as to enable the fuel from the fuel tank to be absorbed effectively by the first and second layers of the charcoal layer, thus preventing the fuel from being released into the air.Type: ApplicationFiled: June 29, 2004Publication date: February 24, 2005Applicant: TOYO ROKI SEIZO KABUSHIKI KAISHAInventors: Kazuya Matsuura, Takashi Sakagami, Kazuhiro Yamaguchi

Patent number: 6811585Abstract: An oil mist filter capable of removing oil mist and separating liquids of low viscosity. A filter section in the oil mist filter is of two-stage construction. The filter section includes a filter body disposed in the upper stage for arresting oil mist and a support body disposed in the lower stage to support the filter body and capable of separating gas fuel. A space is defined below the filter body. When passing through the filter body the oil mist in the gas fuel is arrested by the filter body. The liquid content in the gas fuel is collected below the filter body in the upper stage, and then moves under its own weight along the support body in the lower stage until it is collected in the space. The gas fuel having its liquid content removed is passed through the support body and fed to the engine.Type: GrantFiled: September 10, 2002Date of Patent: November 2, 2004Assignee: Toyo Roki Seizo Kabushiki KaishaInventors: Takashi Sakagami, Kenji Yano

Patent number: 6589319Abstract: A canister having a liquefied fuel treating function capable of flexibly coping with layout restrictions without the need to bend the purging path in the middle. The canister having the liquefied fuel treating function includes a liquid storing case having an introducing path communicating with a fuel tank, and a purging path communicating with air inlet pipes of an engine; and a sucking path, provided in the liquid storing case, and sucking the liquefied fuel stored in the liquid storing case; which sucks up the liquefied fuel onto the purging path side by use of the flow of a fluid through the purging path; wherein the sucking direction of the liquefied fuel within the sucking path is caused to substantially agree with the flow direction of the fluid in the purging path.Type: GrantFiled: October 31, 2001Date of Patent: July 8, 2003Assignee: Toyo Roki Seizo Kabushiki KaishaInventors: Kouichi Ikuma, Takashi Sakagami, Takenori Suzuki
