Publication number: 20100280463Abstract: A valve body, e.g. a valve body adapted to be disposed in a connector to be connected to a catheter, has an opening/closing part which opens upon inserting a member into the opening/closing part and which closes upon withdrawing the member from the opening/closing part. The valve body includes a main body part made of a silicone rubber and a surface layer disposed on a surface of the main body part. This surface layer serves as a sliding surface which, when a guide wire has been inserted into the opening/closing part, slides on the guide wire. The surface layer is constituted mainly of silicon oxide and hence improves the sliding properties of the guide wire. Thus, the valve body is reduced in the resistance of sliding on the guide wire.Type: ApplicationFiled: July 16, 2010Publication date: November 4, 2010Applicant: TERUMO KABUSHIKI KAISHAInventors: Hiraku MURAYAMA, Yuuki Yoshifusa

Publication number: 20090184275Abstract: A fluid handling device, such as a needlefree access device, includes a housing having an inlet and an inlet channel; and a flow control member comprising a combination outlet, biasing and piston member. The flow control member includes a piston section moveable between a closed position in which the piston section is in the inlet channel and an open position in which the piston section is inside the housing below the inlet channel but allows fluid to flow through the inlet channel; a biasing section connected to the piston section that normally biases the piston section into the inlet channel; and an outlet section connected to the biasing section having an outlet fitting in fluid communication with the inside of the housing. The piston section, biasing section and outlet section are connected together such that they can be handled as one piece when assembled with the housing to make the needlefree access device.Type: ApplicationFiled: March 10, 2009Publication date: July 23, 2009Inventors: Ricky R.

Publication number: 20090158589Abstract: A slide valve apparatus includes a first member having a first fluid channel for allowing a fluid to flow therethrough, a second member sliding along the first member and having a second fluid channel formed in a manner to communicate with the first fluid channel, and a first elastic membrane formed in the sliding surface along which the second member and the first member slide relative to each other and having a first communicating hole communicating with the first fluid channel. In manufacturing the slide valve apparatus, a gas is spurted from the open edge of the first fluid channel in at least a stage between the start up of the step of forming the elastic membrane and the end of the step of baking the elastic membrane so as to form in the elastic membrane the communicating hole communicating with the first fluid channel.Type: ApplicationFiled: February 20, 2009Publication date: June 25, 2009Inventors: Masahiro KUWATA, Hajime Sudo, Takehiko Kitamori

Publication number: 20090156071Abstract: A primary exhaust bypass for a water-borne vessel having a seat member and a closure member coupled to the seat member, wherein the seat and closure members are configured to seal against exhaust leakage in the closed position and to allow exhaust leakage in the opened condition, and a locking mechanism, wherein the bypass is configured to open when the vessel lists a predetermined amount. A method of bypassing a blocked primary exhaust system may include establishing a bypass exhaust route, providing a normally-closed bypass mechanism at a distal portion of the bypass exhaust route, and changing the orientation of the bypass mechanism with respect to gravity, which may allow the bypass mechanism to open.Type: ApplicationFiled: December 12, 2008Publication date: June 18, 2009Applicant: LESEMAN DAVIS LLCInventors: Joseph B.

Publication number: 20090114658Abstract: A float-based automatic drain valve automatically drains fluid from a compressed air cylinder; the cylinder includes a chamber with an inlet and an outlet. The inlet is formed at the top of the chamber and connects to a low point of the compressed air cylinder to receive fluid therefrom. The outlet is formed at the bottom of the chamber for discharging the fluid. A buoyant stopper disposed within, and not attached to, the chamber, seals the outlet when insufficient fluid is present within the chamber to float the buoyant stopper. Further, the buoyant stopper unseals the outlet and discharges the fluid when buoyancy of the stopper within the fluid overcomes forces seating the buoyant stopper at the outlet.Type: ApplicationFiled: October 31, 2008Publication date: May 7, 2009Inventor: David Kumhyr

Publication number: 20090114873Abstract: A diaphragm for use with a valve includes a body having a central portion including an outer central portion and offset by an angled portion from an outer portion. The central portion is to be disposed at a position adjacent a valve seat and displaced into engagement with the valve seat to affect fluid flow. The body deforms substantially at the outer central portion and angled portion during displacement of the central portion by the valve and reacts substantially unilaterally to prevent vibration of the diaphragm during fluid flow past the valve seat.Type: ApplicationFiled: November 5, 2007Publication date: May 7, 2009Inventors: Richard Anagnos, Dennis Eugene O'Hara, Ernest Souliere

Publication number: 20090108107Abstract: When a fuel injection valve is mounted on an engine, a distance between a core and an armature during non-energization of a coil can be prevented from becoming narrow. The coil is arranged inside the core, and a body is fixedly secured at its one end to an end of the core. A housing is arranged outside the coil with its one end abutting a cylinder head. A cap is arranged at the other end of the housing, and abuts at its side opposite to the housing with a fastening unit. The armature is arranged for reciprocation inside the body, and is magnetically attracted to the magnetized core. A gap is formed between the housing and the body, with the cap and the core being fixed to each other, and upon mounting the valve on the engine, the housing and the fastening unit abut the cylinder head and the cap, respectively.Type: ApplicationFiled: April 29, 2008Publication date: April 30, 2009Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Kazunori KITAGAWA, Kouichi OJIMA, Yoshihiko ONISHI
