摘要： Fuel is pressurized by the expansion and contraction of a pump chamber defined inside a casing according to the rotation of a power input shaft which penetrates from the outside of the casing into its inside. A first seal member is provided between the casing and the power input shaft and prevents escape of fuel which is inside the casing, and a second seal member is provided in series therewith. Further, leakage of fuel to the outside of the casing from the second seal member is prevented by the provision of a drain conduit which drains fuel which has leaked into a space defined between the first seal member and the second seal member.

摘要： Each cylinder of a multi-valve engine is provided with a bifurcate induction port which has a partition wall; a fuel injector which injects fuel toward the partition wall so that fuel is distributed into the two branches which lead to the inlet valves; and a flow control valve is disposed upstream of the partition wall and formed with one or more apertures which when the valve is closed, direct a flow or flows of air which pass close to the partition wall, entrain the injected fuel and induce a turbulent mixing action which forms an ignitable cloud of air-fuel mixture in close proximity to the spark plug.

摘要： This device diagnoses whether or not a fuel pump which supplies fuel to an engine has failed. The pump includes a plurality of pressure chambers which in turn discharge fuel according to the rotation of an input shaft which turns together with the engine. The supply capacity of the fuel pump when one of the pressure chambers has failed so as not to be able to discharge fuel is set to a value lower than the maximum value of the fuel supply amount which is required by the engine. A mechanism is provided which decides whether or not the fuel supply requirement of the engine is being satisfied, and failure of the fuel pump is diagnosed based upon the result of this decision. Further, accurate diagnosis can be performed by detecting the power output of the engine for each cylinder individually, and by deciding upon fuel supply insufficiency for each cylinder individually according to variation of the output power for each cylinder individually.

摘要： A cam plate pump comprises a pressurizing chamber formed by a bellows which elongates and contracts along a center axis parallel to the input shaft of the pump. The cam plate rotates together with the input shaft, and compresses the bellows via a piston. A mechanism for guiding the piston along the center axis, and a mechanism for blocking the rotational torque acting on the bellows via the piston are provided. These mechanisms prevent a bending load or twisting load from acting on the bellows.

摘要： A torque is transmitted between a fluid pressure pump driven together with drive of a vehicle, and a fluid pressure motor that rotates together with driven wheels. The fluid pressure motor has two ports, and rotates in accordance with the direction of fluid supply to the ports. Fluid is circulated from one port to the other according to the input of rotation torque from the driven wheels. A high pressure flowpath connected to the pump outlet, and a low pressure flowpath connected to the pump inlet, are connected to these ports, and the connection direction is reversed when the rotation direction of the drive wheels is reversed. The low pressure flowpath is therefore always at low pressure regardless of the rotation direction of the drive wheels, and by controlling the pump supply flowrate so as not to exceed a predetermined value, torque is not transmitted when the vehicle is running at high speed.

摘要： A hydraulic pump is mounted to a cylinder block of an internal combustion engine and powered by said engine, and a hydraulic motor for operating an engine accessory, such as alternator, compressor of air conditioner and the like, is mounted to the cylinder block and driven by a highly pressurized oil fed by the hydraulic pump. The cylinder block is formed with an oil flow passage through which the highly pressurized oil is conveyed from the hydraulic pump to the hydraulic motor. An oil return passage is provided for returning the oil from the hydraulic motor to the hydraulic pump. If desired, the oil return passage may be defined in the cylinder block.
