  • Publication number: 20120245774
    Abstract: A rotation speed controller performs a rotation speed control to allow the rotation speed of a first rotating electrical machine to be equal to a start up target value, when an internal combustion engine is started while a frictional engagement device is disengaged. An engagement controller controls a non-synchronization engagement of the frictional engagement device and allows the frictional engagement device to be in a direct engagement state when performing the rotation speed control. A start up instruction unit gives a start up instruction with respect to the internal combustion engine on condition of being directly engaged. The rotation speed controller sets the start up target value so that a rotation speed at the time of a direct connection, which is a rotation speed of the engine while in direct engagement, becomes a start up rotation speed that is set within a startable rotation speed range of the engine.

  • Publication number: 20120244992
    Abstract: A driving device with an input member connected to an engine, an output member connected to wheels, first and second rotating electrical machines, a differential gear unit including at least three rotational elements, and a control device. The control device includes a differential rotation reducing control, an engagement control, and a start up control that changes the rotation speed of the first rotating electrical machine, which allows the internal combustion engine to have a rotation speed at which starting is possible, made as a target value, when in direct engagement. The differential rotation reducing control changes the rotation speed of the first rotating electrical machine with the upper limit and the lower limit of a starting torque output range, which is a rotation speed range in which the torque necessary for starting the internal combustion engine may be output by the first rotating electrical machine, made as limits.

  • Patent number: 8226377
    Abstract: When a press jig is inserted into a jig insertion hole, an O-ring attached to the outer peripheral surface of the press jig is prevented from being caught on an air supply port opening to the inner peripheral surface of the jig insertion hole and damaged. In a sealing pump-up device 10, the opening diameter of an air supply port 58 opening to the inner peripheral surface of a jig insertion hole 44 provided at one end of an air supply path 60 is set smaller than the strand diameters of an O-ring 72 and an O-ring 96. Consequently, the width at the edge of the air supply ports 58 on which the O-rings 72, 96 may possibly be caught can be made sufficiently smaller than the strand diameter of the O-rings 72, 96.

  • Patent number: 8016002
    Abstract: A sealing/pump-up device for tire that not only ensures the storability of sealing agent but also realizes rapid supply of sealing agent into a pneumatic tire. By insertion of insert part (60A) of jig (60) in jig insertion aperture (42) of sealing device (10), aluminum seal (30) is burst through by means of boring member (50) to thereby drive the same in the container. As the distal end of the insert part (60A) locates in the vicinity of upper wall surface within liquid agent container (18), a compressor unit is operated to thereby supply compressed air into the liquid agent container (18). As the end portion of first passage (62) provided in the jig (60) lies in a position superior to the liquid surface of sealing agent (32), the compressed air realizes rapid supply of the sealing agent (32) into a pneumatic tire without surfacing in the form of bubbles through the sealing agent (32).

  • Patent number: 7926521
    Abstract: To be able to simply carry out an operation of repairing a punctured pneumatic tire, to be able to inject a necessary amount of a sealing agent firmly into the pneumatic tire even when the apparatus is used in an inclined state and to prevent clogging of the sealing agent and leakage of a liquid by being pressurized. A pump up apparatus 30 is an apparatus for injecting a sealing agent in a liquid state into a punctured pneumatic tire 38, thereafter, supplying compressed air into the pneumatic tire 38 to elevate an inner pressure thereof. The pump up apparatus 30 includes a sealing agent vessel 34 accommodating the sealing agent, a sealing agent injecting pump 42 for sucking the sealing agent from the sealing agent vessel 34 to feed it to the pneumatic tire 38, and a compressor 44 for pressurizing and sending air to the pneumatic tire 38.

  • Patent number: 7891385
    Abstract: To reliably supply a predetermined amount of sealing agent into a pneumatic tire even if the device is inclined and after the predetermined amount of sealing agent is supplied, to automatically start feeding compressed air into the pneumatic tire. In pumping device 30, when compressed air is supplied to air chamber 54, internal pressure of air chamber 54 increases, and as the internal pressure of air chamber 54 rises, a contained volume of air chamber 54 increases while a contained volume of liquid container 52 decreases. Thus, sealing agent 100 in an amount corresponding to the amount corresponding to the reduction in the contained volume of liquid container 52, is forcibly discharged from discharge outlet 64 and the discharged sealing agent 100 is injected into tire 90.
