Abstract: A solenoid-operated valve particularly for use in a speed-responsive power steering system on a motor vehicle comprises a valve housing having two ports opening into a bore in the housing, a spool axially slidable in the bore and slot defining a bypass passageway extending between the two ports and variable in cross section upon axial movement of the spool. The spool is spring-biased in a direction to close the bypass passageway, but attractable by an energized solenoid to open the bypass passageway when the solenoid is supplied with an electric current dependent on the speed of travel of the vehicle. The spool has therein a restrictor disposed in the bypass passageway adjacent to the slot to restrict the flow of a fluid through the bypass passageway into and out of the bore in the housing.

Abstract: A spark timing control system for an internal combustion engine features an ignition device, a power increase detector, a control device, and a temperature detector. The ignition device produces a spark in a combustion chamber of the engine. The power increase detector senses an increase in the output power required of the engine. The control device is connected to the ignition device for controlling timing of the spark, and is also connected to the power increase detector for retarding the spark timing in terms of engine crank angle when the engine is required to increase its output power. The temperature detector senses the temperature of engine coolant and suspends the retardation of the spark timing due to the engine power increase in response to the temperature of engine coolant.

Abstract: In a power steering device for a vehicle, a first spool valve member is slidably received in a valve housing and is supplied with a steering pressure generated in response to a manual steering torque. A second spool valve member is slidably received in the first spool valve member and is supplied with a control pressure depending upon a vehicle speed. Bypass means is formed on the first and second spool valve members to be actuated by the control pressure to communicate both cylinder chambers of a manual steering torque supplementing hydraulic actuator with each other. Relative displacement between the first and second spool valve members is caused by the steering pressure to act to close the bypass means.

Abstract: A continuously variable speed converter is provided wherein a plurality of balls are interposed between a pair of friction discs for transmitting rotation of an input shaft to an output shaft connected with a fluid pump. A speed change mechanism is arranged to tilt the rotational axis of each of the balls in each plane, including the axis of the input shaft, to thereby change the output/input speed ratio. Disposed within a main housing carrying the input and output shafts is the fluid pump, which also serves as a pressuring means responsive to fluid delivered by itself so as to apply to the output shaft a thrust force corresponding to the pressure of the fluid, so that efficient power transmission without slippage may be provided between the friction discs and the balls.

Abstract: A continuously variable speed converter is incorporated in a main housing of a fluid pump and is drivingly connected at an output shaft thereof to a pump rotor so as to transmit the driving power of an engine to the pump rotor at various output/input speed ratios. An actuator is operatively connected at its piston to a speed change mechanism of the speed converter and is responsive to pressurized fluids, which are delivered from the pump, respectively, through and not through a throttle element provided on an outlet passage of the pump. The piston is biased by means of a spring to operate the speed change mechanism to maintain constant the pressure difference between fluids before and behind the throttle element, so that fluid may be delivered from the pump approximately at a predetermined flow rate regardless of changes in engine rotational speed.

Abstract: An air bag device designed to protect passengers in a vehicle. In the device, an inflatable gas bag is inflated by a gush of high pressure gas which is discharged from a gas supply source through a gas discharging pipe and guided by a housing. The housing has defined therein large openings to introduce ambient air, and has mounted, at the region where the inflatable gas bag are mounted, gas permeable supporting plates and valve members urged against the gas-permeable supporting plates. The gush of the high pressure gas discharged through the gas discharging pipe sucks in and mixes with the ambient air introduced through the large openings in the housing. The resultant air-high pressure gas mixture passes through the supporting plates, opens the valve members and then, flows into the inflatable bag to inflate the latter.

A nozzle having a plurality of nozzle holes opened into the conduit is interposed between the rupture plate and the conduit. A spool is slidably fitted to the nozzle in such a way that it may normally close a predetermined number of nozzle holes, but may be displaced away from the nozzle to open them in response to the increase in pressure in the nozzle chamber when the rupture plate is ruptured in case of a collision, whereby the flow rate of the high pressure gas flowing into the inflatable safety bag may be suitably controlled so as to prevent very rapid expansion of the bag resulting in the injury to an occupant.
