The staple cartridge comprises a cartridge body, an elongate slot, and a deck. The deck comprises a first deck surface and a second deck surface, wherein one of the first deck surface and the second deck surface is stepped up from the other one of the first deck surface and the second deck surface. The staple cartridge further comprises a plurality of first staple cavities, a plurality of second staple cavities, and a plurality of third staple cavities, a driven element, a securement member releasably engaged with the deck, an implantable portion, and a plurality of staples deployable concurrently into tissue captured between the anvil and the staple cartridge.

The invention relates to a coolant pump having an impeller which is arranged on a pump impeller shaft and having a drive device for the impeller, which drive device has a mechanical drive and an electric-motor drive. The impeller shaft is divided into a driving section and a driven section, and an openable and closable clutch is arranged between the driving section and the driven section. Operation of the coolant pump by either the mechanical drive or the electric-motor drive can be dependent upon a predetermined speed of threshold of rotation of the impeller, and/or upon a predetermined power usage threshold.

A temperature control device for an internal combustion engine includes a determining drive processor and an abnormality determining processor. The determining drive processor drives an electric pump when the difference between the water temperature and the ambient temperature is greater than or equal to a predetermined value while the electric pump is stopped. The abnormality determining processor determines that at least one of the water temperature sensor and the ambient temperature sensor is abnormal on a condition that the decrease amount of the water temperature. The determining drive processor includes a stopping processor, which stops driving of the electric pump when the cumulative amount of coolant discharged from the electric pump reaches the predetermined cumulative amount with driving of the electric pump. The predetermined cumulative amount is set according to the volume of the engine passage between the inlet of the engine passage and the water temperature sensor.

A system and method of thermal management for an engine are provided. The system includes an engine, an electrical water pump, and a controller. The controller has a processor and tangible, non-transitory memory on which is recorded instructions. Executing the recorded instructions causes the processor to continuously monitor the temperature of the cylinder head and the temperature of the coolant. If the monitored temperatures of the cylinder head and the coolant are below predetermined thresholds, the processor executes a first control action, in which the pump remains off and the coolant remains stagnant. If either of the monitored temperatures of the cylinder head or coolant reaches the respective predetermined threshold, the controller initiates a second control action, which requires the controller to signal the pump to turn on and circulate coolant. The controller then determines the desired operating speed of the electrical water pump based on engine load.

A automotive coolant pump includes a pulley wheel fixedly supported by a rotatable rotor shaft. A shaft sealing separates a dry pump section from a wet pump section. A pump wheel is supported in the wet pump section by the rotor shaft and is axially slidable between a pumping and a non-pumping position. An actuator is arranged in the dry pump section. A linear actuator rod is arranged in parallel to and eccentrically with respect to the rotor shaft. The linear actuator rod comprises a dry and a wet section. A rod sealing is actuated by the actuator and separates the dry from the wet of the linear actuator rod. A shift ring is arranged so as to be axially shiftable and rotatably fixed at the rotor shaft in the wet pump section. The shift ring is moved axially by the actuator rod and axially moves the pump wheel.

A system for operating at least a pair of pumps using a driver. The driver can be coupled to a first portion of a first drive shaft that is not positioned in within an interior area of a thermal fluid tank of a first thermal circuit. A magnetic coupling can couple the first portion to a second portion of the first drive shaft that is within the thermal fluid tank. Rotational displacement of the first portion of the first drive shaft can be translated, via the magnetic coupling, to the second portion of the first drive shaft to drive a first fluid pump. The first portion of the first drive shaft can also be coupled to a second drive shaft by a clutch, the second drive shaft being used to operate a second fluid pump that provides a force for circulating a second thermal fluid of a second thermal circuit.

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.

A cooling-water temperature is detected at startup of an engine. When the detected temperature falls below a set water-temperature, a water pump is stopped independently of a normal control on rotational frequency of the water pump depending on engine operational state. Calculated is a total heat amount required for raising the current water-temperature to the set water-temperature, and integrated is an heat amount lost by the cooling water from the engine from the startup. When an integrated value reaches the total heat amount, the water pump is operated for a required time to uniformize temperature distribution of the cooling water. Then, the cooling-water temperature is detected again. If the detected temperature is still below the set water-temperature, the same control is repeated; if the detected temperature is equal to or greater than the set water-temperature, the normal control is restored.
