Publication number: 20100263210Abstract: A method of improving hot water supply performance of a water heater is provided. The method includes coupling an outlet port of a water tempering device to the cold water inlet port of a water heater for delivering cold water from the cold water supply line into the water storage tank. The inlet port of the tempering device is coupled to the hot water outlet port of the water heater for receiving hot water from the water storage tank to the hot water supply line. A conduit of the tempering device is positioned between the inlet and outlet ports of the tempering device for diverting a portion of the cold water delivered from the cold water supply line into the conduit. The tempering device mixes the diverted cold water with the hot water received from the water storage tank, and delivers the mixed water into the hot water supply line.Type: ApplicationFiled: June 25, 2010Publication date: October 21, 2010Applicant: Bradford White CorporationInventors: Michael W.

Publication number: 20100252002Abstract: In a fuel injector, a body has formed therein a spray hole and a fuel supply passage. Fuel supplied to the fuel supply passage is delivered to the spray hole. A fuel pressure sensor produces a signal indicative of a pressure of the fuel. First terminals are attached to the fuel pressure sensor, and include a terminal for outputting the signal. The fuel pressure sensor is threadedly installed in the body while the plurality of first terminals are rotated about a preset axis. A connector includes a housing attached to the body, and second terminals supported by the housing for external electric connection of the fuel pressure sensor. Electrodes are each arranged to extend around the preset axis in a circular arc. Each of the electrodes electrically connects a corresponding one of the first terminals to a corresponding one of the second terminals.Type: ApplicationFiled: April 2, 2010Publication date: October 7, 2010Applicant: DENSO CORPORATIONInventors: Tomoki Fujino, Jun Kondo, Yutaka Miyamoto

Publication number: 20100249723Abstract: Some embodiments disclosed herein relate to a medical connector having a backflow resistance module configured to prevent fluid from being drawn into the connector when a backflow inducing event occurs. In some embodiments, the backflow resistance module can include a variable-volume chamber configured to change in volume in response to a backflow-inducing event and a check valve configured to resist backflow. In some embodiments, the medical connector can include a fluid diverter configured to direct fluid flowing through the medical connector into the variable volume chamber to prevent fluid stagnation therein. In some embodiments, the medical connector includes a body member, a base member, a seal member, a support member, and a valve member.Type: ApplicationFiled: March 23, 2010Publication date: September 30, 2010Applicant: ICU Medical, Inc.Inventor: Thomas F.

Patent number: 7802584Abstract: A fuel injector comprising a hollow body for housing a metering valve with a calibrated pipe for outlet of the fuel from a control chamber. The calibrated pipe is normally kept closed by a shutter controlled by an electromagnet comprising a magnetic core and an electric coil housed in an annular slot of the core. The coil outer cylindrical surface forms a gap with the annular slot so as to be lapped by the fuel coming out of the calibrated pipe. The coil comprises a bobbin having a pair of appendages for supporting electric supply plugs, which are englobed at least in part in a block of non-magnetic material. The bobbin has a substantially cylindrical rib, one flange adjacent to an end portion of the plugs, and another flange having a smaller diameter that forms a passage for the fuel between the calibrated pipe and the gap.Type: GrantFiled: December 27, 2006Date of Patent: September 28, 2010Assignee: C.R.F.
