摘要： A cooling apparatus includes a circulation circuit, a pump, a flow rate adjustment valve, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a stopper that moves between a restriction position and a retraction position. The controller is configured to execute, when maintaining the open degree of the flow rate adjustment, a preparatory process of moving the stopper to the restriction position after arranging the stopper at the retraction position and arranging the valve member further in the valve-closing direction than the stopper through control of the pump discharge amount.

摘要： A flow passage device includes a circulation flow passage, a swing valve provided in the circulation flow passage, an energizing part, and a lock mechanism including a lock pin. The lock pin is configured so as to hinder the swing valve from opening, and to allow the swing valve to open. The swing valve is configured so as to rotate from a first valve position to a second valve position. The lock mechanism is configured so as to set a locked state and to set an unlocked state. The lock pin is configured so as to protrude as being energized by pressure of the fluid on an upstream side of the swing valve, and to retract as being energized by pressure of the fluid on a downstream side of the swing valve.

摘要： A control device for an onboard engine is configured to control the oil discharge pressure of an oil pump and execute, when determining that there may be an abnormality in the control of the oil discharge pressure, a change process that increases the target discharge pressure to a value that is greater than that before it is determined that there may be an abnormality in the control. When a discharge pressure sensor value in a situation in which the discharge pressure is being controlled based on the target discharge pressure increased through execution of the change process does not become greater than or equal to a discharge pressure threshold, the control device sets an upper limit for the engine rotation speed and increases the upper limit as the discharge pressure sensor value increases.

摘要： A cooling apparatus for an internal combustion engine includes a pump, a radiator, a flow rate adjustment valve, a bypass passage, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a valve member biasing component that biases the valve member in a valve-closing direction in which the open degree decreases. The valve member rotates in a valve-opening direction in which the open degree increases when a pressure difference increases between positions upstream and downstream of the valve member in a flow direction of coolant in the circulation circuit and rotate in the valve-closing direction when the pressure difference decreases. The controller increases the pump discharge amount as a target radiator flow rate that is a target of an amount of coolant passing through the radiator increases.

摘要： A cooling device includes an inner passage, an outer passage, an engine-driven pump, an electromagnetic control valve, and a driving circuit that regulates current flowing through the electromagnetic control valve by activating and deactivating a switching element. A cooling controller for the cooling device includes a processing circuit configured to execute an operation process for operating, when the engine-driven pump is driven, the switching element by setting a duty cycle of an activation time to a switching cycle, which is a reciprocal of a switching frequency of the switching element, to be a larger value when a temperature of the internal combustion engine is low than when the temperature is high and a cycle varying process for setting a longer switching cycle when the temperature of the internal combustion engine is less than a preset temperature than when the temperature is greater than or equal to the preset temperature.

摘要： A device seating a valve body with the aid of an urging force of a spring by stopping the operation of a pump, changes over an energization state of a coil of at least one of the liquid shutoff valves which is changed over to the closed-valve state where the coil is energized, and then resumes the operation of the pump. Upon detecting the start of operation of the pump, a valve control unit causes a pump control unit to perform opening-closing force-feed control, where an amount of the cooling liquid force-fed by the pump is set to an amount within such a range that the valve body of the liquid shutoff valves whose coil is energized is not displaced in a valve-opening direction while the valve body of the liquid shutoff valves whose coil is not energized is displaced in the valve-opening direction.

摘要： A cooling control device includes a coolant pump being driven at an internal combustion engine to supply a coolant of the internal combustion engine, a heat exchanger being provided at each of plural flow paths that are formed in parallel to one another, a flow amount control valve controlling the coolant being supplied to the plural flow paths, and a control portion controlling the flow amount control valve. The control portion performs a control in a first supply mode in which the coolant is supplied to a first flow path, and a second supply mode in which the coolant is supplied to a second flow path during a supply of the coolant to the first flow path. The control portion operates a switching control shifting to the second supply mode temporarily in a state of being in the first supply mode, and returning to the first supply mode.

摘要： An assembled battery is formed by combining battery modules. Each battery module includes at least one battery cell and a rectangular box-shaped case that accommodates the at least one battery cell. The battery modules include a first battery module and a second battery module located adjacent to each other. The case of each of the first battery module and the second battery module includes an opposing side surface that is opposed to one of the first battery module and the second battery module. Each opposing side surface includes projections, which are laid out in rows, and ribs, which extend parallel to the layout direction of the projections. The ribs are smaller in height than the first projections. The ribs include connection ribs that connect the projections located in a predetermined range in the layout direction of the projections.

摘要： A connection unit of the present invention includes: a rail member extending in a direction where a plurality of storage elements is aligned; and a plurality of bus bar units each including an engagement portion movable along the rail member in the predetermined direction, and a bus bar fixed to electrode terminals of the storage elements adjacent to each other in the predetermined direction and connected to the engagement portion. The plurality of bus bar units engages with the rail member so as to be aligned in the predetermined direction, and the bus bar units adjacent to each other are provided so as to be movable independently along the predetermined direction. Entire assembly tolerance in the plurality of storage elements aligned in the predetermined direction can be absorbed (permitted) by adjusting distances between the independent bus bar units, thereby making it possible to easily assemble the plurality of bus bars.
