Abstract: When a booster is inoperative, a first atmosphere valve and a second atmosphere valve are both closed to block a communication of an orifice passage with a variable pressure chamber. At the commencement of operation of the booster, the first atmosphere valve opens while the second atmosphere valve remains closed to allow the atmosphere to be introduced into the variable pressure chamber through the orifice passage, followed by an opening of the second atmosphere valve to allow the atmosphere to be introduced into the variable pressure chamber through the second atmosphere valve and the first atmosphere valve. This arrangement allows the occurrence of oscillations of or abnormal sounds from a valve mechanism to be prevented during the initial phase of the brake operation.

Abstract: Apparatus, and an accompanying method for use therein, that utilizes working and stopping servo-controlled hydraulic pistons wherein the stopping piston acts as a controlled mechanical stop for the working piston. Both pistons are spaced apart along and coaxially arranged around a common shaft, with each piston moving in a separate cylinder. The working piston is securely attached to the shaft, while the shaft moves through a central, longitudinal bore of the stopping piston. The stopping piston effectively “floats” in its cylinder and produces a greater force than the working piston. A radially extending stop element, situated on the shaft, has a surface configured to abuttingly engage with a complementary surface on the stopping piston such that the stopping piston, once appropriately positioned, controllably stops continued movement of the working piston in a very short time and over a very short distance with little strain induced in the apparatus.

Abstract: In a heat storage tank, a discharge port of an introduction passage is covered by a cup-shaped collision member constructed by a shield portion and a guide cover. In addition, a mixture protection plate having plural through holes is disposed in a tank body between the collision member and an inner surface of the tank body. Therefore, a high-speed water stream, upwardly injected from the discharge port, collides with the shield portion, and turns its flow direction by an approximately right angle.

Accordingly, it can prevent water stored in the tank body from being mixed even when the injection water stream has a high speed.

Abstract: In a preferred embodiment, a windage tray assembly is mounted to crankshaft bearing caps which connect with oil passages in the windage tray. The passages carry the oil through nozzles directed toward the interior of associated pistons. The arrangement utilizes the windage tray and bearing caps as carriers for piston cooling oil obtained from the bearing caps, which are already supplied with oil for lubricating the bearings. Thus, modifications of an engine design to install a piston cooling system are limited to redesign of the windage tray to a sandwich-like assembly and modification of the bearing caps to conduct oil from the bearings to the windage tray passages. To limit oil pumping energy, oil distribution holes in the bearing caps connect intermittently with crankshaft journal feed passages so the oil is distributed in individually timed streams or sprays directed toward the pistons for a short interval once every revolution of the engine crankshaft.

Abstract: A two-cycle engine having improved performance characteristics includes a block and a cylinder head coupled to the block, the cylinder head defining a cylinder bore and a precombustion chamber. The head of piston located in the cylinder bore divides the bore into first and second variable volume intake chambers. An intake port allows fresh air to be drawn into the variable volume intake chamber and be compressed by the moving piston and delivered to the precombustion chamber. Fuel is added to the compressed air, which is heated, and then delivered to the variable volume combustion chamber. In one embodiment, the piston drives a crankshaft which is mounted both for rotation and for translation. Another embodiment of the invention is a lubricating system for a piston where movement of the piston up and down generates a pumping effect moving lubricant through the piston for lubricating piston rings.

Abstract: An output from each of output rods is converted into an assisting force via a corresponding one of rollers, while an outer peripheral surface of each of the rollers moving together with a control shaft serves as a conversion plane. This output is applied to the control shaft. Hence, as the control shaft is moved in such a direction as to increase valve lift amounts of intake valves, the assisting force can be correspondingly increased. Thus, a suitable assisting force that can act against a thrust force can be applied to the control shaft. As a result, there is no apprehension that a minimum hydraulic fluid pressure will not be ensured on the side of a larger valve lift amount or that responding properties in movements of the control shaft will deteriorate.

The locking and/or unlocking process of the locking element occurs through at least one oil duct that leads to the locking element. Between two pressure chambers in or on the cellular wheel an opening connected with the oil duct is arranged, whose passage to the two pressure chambers is controlled in dependence on the adjusting position of the interior part. This way, the cam shaft adjusting unit can be locked safely.
