Patent number: 9945373Abstract: A pump may have a first chamber and a solenoid coil to control movement of a first valve member. A second chamber may have a second valve member to control fluid moving into a third chamber. A first fluid passageway may link the first and second chambers, a second passageway may link second and third chambers and a third passageway may link third and fourth chambers. After pressurizing the third chamber causing fluid to flow into and leave a fourth chamber, the third chamber depressurizes due to downward movement of a plunger. Upon depressurization with a solenoid coil energized, second valve member floats and then moves against a valve seat. While the second valve member is moving toward the valve seat, the solenoid coil is de-energized causing the first valve member to move and strike the second valve member when the second valve member is moving at maximum velocity.Type: GrantFiled: June 21, 2016Date of Patent: April 17, 2018Assignees: DENSO International America, Inc., DENSO CORPORATIONInventors: Tsutomu Furuhashi, Rebecca Spence, Joseph Lubinski, Dhyana Ramamurthy, Kaoru Oda

Patent number: 8979514Abstract: A pump includes a pump casing defining a first chamber and a second chamber, and fluid moves from the first chamber to the second chamber during a stroke. The pump also includes a needle that is movably disposed in the first chamber and a valve carriage that is movably disposed in the second chamber. The valve carriage includes an internal stop, and the valve carriage also includes a cavity therein that is partially defined by the internal stop. The pump further includes a valve that is movably disposed within the cavity of the valve carriage, and the valve is operable to be impacted by the needle during the stroke. Also, the needle is operable to impact the valve carriage during the stroke. Moreover, the valve is operable to impact the internal stop during the stroke at a time different from the needle impacting the valve carriage.Type: GrantFiled: January 23, 2012Date of Patent: March 17, 2015Assignees: DENSO International America, Inc., Denso CorporationInventors: Tsutomu Furuhashi, Dhyana Ramamurthy, Joseph Lubinski, Rebecca Spence

Publication number: 20090235994Abstract: A pressure relief mechanism may utilize a casing that defines an internal cavity, a fluid inlet, and a fluid outlet. A first valve may reside within the internal cavity to permit fluid flow in one direction and further utilize a first valve carriage and a first valve spring that forces the first valve carriage against a first end of the casing internal cavity, over the fluid inlet. The first valve spring may reside against a second end of the casing cavity. A second valve may reside within the internal cavity and utilize a second valve carriage, a second valve body, and a second valve spring that biases the second valve body against the first valve body, the second valve permitting fluid flow opposite to the flow of the first valve.Type: ApplicationFiled: January 12, 2009Publication date: September 24, 2009Applicant: DENSO International America, Inc.Inventors: Joseph Lubinski, Patrick Powell

Patent number: 7506636Abstract: A fuel pump module within a fuel tank employs at least one fuel pump, while in the case of additional fuel pumps, a manifold receives all pumped fuel and directs it into a surrounding fuel filter within a filter case. A check valve is adjacent the filter case at a first location and a pressure regulator is adjacent the check valve. With the check valve located between the filter case and the pressure regulator, high fuel pressures may be maintained in the engine supply line when the engine is shut off, while during engine operation the pressure regulator may relieve excessive fuel pressure and deliver fuel to the engine through an engine supply line. A jet pump supply line exits the filter case at a second case location and supplies fuel to one or more jet pumps, such as a fuel pump module reservoir jet pump.Type: GrantFiled: February 6, 2007Date of Patent: March 24, 2009Assignees: DENSO International America, Inc., Denso CorporationInventors: Joseph Lubinski, Hideto Takahashi, Tatsuya Matsumoto

Patent number: 6418273Abstract: A portable video compact disc player capable of playing both audio compact discs and MPEG-1 video compact discs is provided. A system control determines the type of signal that is being produced from the disc and controls the processing of that signal. If the signal is audio the system control directs the audio out to the speakers or alternative audio output ports. If the information is encoded MPEG-1 audio/video the system control sends the signal to the digital signal processing section. The digital signal processing section produces an MPEG-1 audio signal and a MPEG-1 video signal. This information is further processed and decoded by an MPEG audio/video processor then sent directly to a display screen through a control circuit board. The power consumed is minimized by reducing the number of semiconductor devices used to display the signal and by limiting the power supplied to the backlight when the device is being operated on DC power.Type: GrantFiled: September 7, 1999Date of Patent: July 9, 2002Assignee: The Original San Francisco ToymakersInventors: Joseph Lubinski, Saul B.
