    摘要: A valve operating device for an engine having at least two engine valves per cylinder, the valve operating device enabling both valve timing and valve-lift characteristic to be varied depending on engine operating conditions, includes a camshaft, at least one cam pair including a low-speed cam and a high-speed cam, each operating an associated valve of at least two engine valves included in a cylinder, a main rocker shaft supported on a cylinder head, a sub rocker shaft, and at least one rocker arm set. The rocker arm set includes a low-speed rocker arm having a first follower driven by the low-speed cam and oscillatingly supported by the main rocker shaft and mounting thereon the sub rocker shaft, and a high-speed rocker arm having a second follower driven by the high-speed cam oscillatingly supported by the sub rocker shaft. The second follower is closely juxtaposed to the first follower and located within a dead space defined in the outside of the engine valves included in the engine cylinder. The at least one rocker arm set includes two adjacent rocker arm sets disposed between the associated two cylinders adjoining to each other. One of the adjacent rocker arm sets has a symmetric shape with respect to the other. The low-speed rocker arm included in the one rocker arm set and the low-speed rocker arm included in the other rocker arm set are supported on the same divided rocker shaft member.

    摘要: A variable valve actuation (VVA) apparatus is disclosed. The VVA apparatus can keep an engine cylinder valve closed. Rotating a camshaft in timed relation with a crankshaft of the engine causes an eccentric crank cam to move a link or crank arm, thereby causing one end of a rocker arm to reciprocate. This causes the other end of the rocker arm to reciprocate. The reciprocating motion of the other end of the rocker arm is transmitted via a link to a valve operating (VO) cam, thereby causing the VO cam to pivot to push a valve lifter for opening the associated cylinder valve. An eccentric circular cam, fixed to a control rod, supports the rocker arm for rotation relative thereto in such a manner that rotation of the control rod causes a pivot center of the rocker arm to move, thereby changing position of the VO cam relative to the valve lifter. The change in the position of the VO cam causes its valve lift diagram to change. The VO cam has a base circle portion that extends over a predetermined angle with respect to the center of pivot of the VO cam and the contiguous ramp portion. A predetermined valve clearance exists between the VO cam and the valve lifter when the base circle portion faces the valve lifter. When it is desired to keep the associated cylinder valve closed, the control rod is rotated to establish a state wherein the VO cam pivots to bring not only base circle but also the ramp portions into facing relation with the valve lifter. In this state, the maximum cam lift of a cam lift diagram is greater than zero and less than the valve clearance.

    摘要: A drive shaft is synchronously driven by an internal combustion engine. A cylindrical hollow cam shaft is rotatably disposed about the drive shaft. The cam shaft has thereon a cam which actuates a valve of the engine. A first flange is formed on one end of the cam shaft. A second flange is connected to the drive shaft to rotate therewith. The second flange faces the first flange. First and second radially extending grooves are formed in mutually facing surfaces of the first and second flanges respectively. The first and second grooves are arranged at opposite sides with respect to an axis of the drive shaft. An annular disc is disposed between the first and second flanges. The annular disc has first and second pins which are slidably engaged with the first and second grooves respectively. A control housing rotatably receives therein the annular disc. The control housing is pivotal in a direction perpendicular to an axis of the drive shaft and has therein a cam receiving circular opening. A control shaft has thereon a circular eccentric cam which is slidably received in the cam receiving circular opening of the control housing. A pair of annular flanges are provided on the control shaft to intimately put therebetween a thicker portion of the control housing thereby to suppress an undesired axial displacement of the control housing on and along the control shaft.

    摘要: In a high-temperature regenerator which has vertical liquid pipe groups in the proximity of which a combustion flame and combustion gas from a burner pass and a double can wall which communicates with upper and lower portions of liquid pipes forming the vertical liquid pipe groups and is arranged at a position of a furnace wall and which heats and concentrates a diluted absorption solution passing through the vertical liquid pipe groups and the double can wall, a solution inlet for sprinkling the diluted absorption solution in an open state is provided above liquid pipes arranged on a side opposite to the burner. Since the sprinkled diluted absorption solution collects the heat of an exhaust gas while it falls to increase its temperature, when it flows into the other liquid pipes, it boils immediately and its circulation flow is activated by boiling. Therefore, total heat transfer coefficient can be increased, a local rise in the temperature of the liquid pipe groups and the can wall can be avoided, and such inconvenience as a corrosion accident and the crystallization of a solution caused by this rise in temperature can be prevented.

    摘要: A cylinder valve control stem for a vehicle drivetrain including a transmission and an engine having a variable valve control mechanism which can vary valve lift diagram in response to a control signal. A controller develops the control signal in response to varying operating condition of the engine. The controller derives, upon initiation of a shift in the transmission, engine speed to be established after completion of the shift and corrects the control signal such that the variable valve control mechanism provides one of various valve lift diagrams whose predetermined value in engine speed is not exceeded by the derived engine speed.

    摘要: The electron multiplying device according to this invention comprises an electron multiplying unit including dynodes arranged in a plurality of stages. The electron multiplying unit has an incidence opening for an energy beam to be multiplied to enter through, and has the proximal end secured to a base. There is provided a casing for housing the electron multiplying unit. The forward edge of the casing is secured to the base, and a space defined by the base and the casing houses the electron multiplying unit. The casing has an entrance window formed at a position opposed to the incidence opening. Energy beams enter the electron multiplying unit through the entrance window, but the electron multiplying unit itself is housed in the casing to be protected from surrounding air flow and unnecessary energy beams not to be measured.
