Abstract:
A cover is laterally mounted on an inner assembly which is a unit including all structural elements except for the cover. The cover is fixed to the inner assembly at three portions. A fitting projection provided on the upper surface of a nozzle base is received in a fitting hole formed in the upper surface of the ceiling of the cover. A pair of opposed engaging pieces are formed on the lower surface of a cylinder and the upper surface of a valve assembly, respectively. An engaging piece engaging with a space between the opposed engaging pieces is formed on the lower end of the cover. A horizontal engaging groove is formed in the upper surface of the nozzle base behind the fitting projection on the nozzle base and a projection engageable with the engaging groove is formed on the inner surface of the ceiling of the cover.
Abstract:
A liquid container to which a cylinder of a manually operated push type dispenser is attached, is so shaped that it can be held with fingers except for the thumb. An assembly is provided between the cylinder and a push button fixed to a distal end of a piston for preventing the push button from rotating. A flange is integrally formed with the cylinder to prevent the slipping of the fingers holding the container and oriented in substantially the same direction as an orifice of the push button.
Abstract:
A slip control device for a vehicle provided with an internal combustion engine, wherein an engine output torque is controlled independently of a depression of the accelerator pedal so that slip at the driving wheels of the vehicle is controlled. A stand-by means is provided and operates, upon a prediction of an occurrence of slip at the vehicle wheels, to close the throttle valve to a stand-by degree of opening thereof before the occurrence of the slip. The stand-by degree of opening of the throttle valve is controlled in accordance with an engine torque of the engine when the occurrence of slip is predicted. Thus the occurrence of slip is effectively prevented and a good acceleration performance obtained.
Abstract:
An automatic speed control apparatus for controlling the running speed of a vehicle at a constant set speed includes an auxiliary intake passage providing direct communication between portions of a main intake passage upstream and downstream from a throttle valve so as to bypass the throttle valve, an auxiliary intake air valve adapted for controlling the flow rate of air in the auxiliary intake passage, and a fuel supply cut-off means for suspending the supply of fuel to the engine from a moment at which a fuel supply cut-off condition is met, which requires the throttle valve to be set at the minimum opening position and the engine speed to be higher than a predetermined fuel supply cut-off engine speed, until the moment at which a predetermined fuel supply recovery condition is met. An actuator for actuating the throttle valve is controlled so as to vary the degree of opening degree of the throttle valve and enable the vehicle to run at the constant set speed. The auxiliary intake air valve is controlled in such a manner that the flow rate of air in the auxiliary intake passage is reduced before the fuel supply cut-off condition is met during motion of the vehicle under the control of the automatic driving apparatus. The rate of fuel supply to the engine has therefore been reduced before the fuel supply is actually cut-off so that the amount of change in the engine output torque and, hence, the level of shock produced by the change in the engine output torque are reduced when cut-off of the fuel supply is executed.
Abstract:
A cruise control system for a vehicle having an internal combustion engine is provided with a throttle valve operated by a diaphragm actuator irrespective of a depression of an accelerator pedal by an operator of the vehicle. The system is provided with a control circuit for controlling an electric signal applied to the actuator. A fixed level signal is first applied to the actuator for a short period after a cruise mode operation has commenced, so that the diaphragm is quickly moved to prevent a temporary decrease in the vehicle speed. After the elapse of the predetermined time, the level of the electric signal is controlled by feedback so that the vehicle speed is controlled to a target speed. A feedback gain initially has a first value for a period after the feedback control is commenced and then has a second value which is smaller than the first value. Furthermore, the feedback gain may have a third value at a transient state from a condition where the feedback gain has the first value and a condition where the feedback gain has the second value.
Abstract:
A cylinder extends into a container containing fluid to be dispensed and includes a pressure accumulating valve at the internal end. A piston sliding in the cylinder includes an air suction valve at the internal end and a pressure chamber is formed between the piston and the cylinder. An elastic piece is axially flexible and is attached to the bottom of the piston. The air suction valve has an axially flexible valve body. A stem fixed at one end to the bottom of the elastic piece is extended into the piston at the other end, and has a pushing part at the other end to release the air suction valve from the valve seat by contacting the valve body when the elastic piece is moved toward the air suction valve.
