Title: Self-travelling vehicle
Inventor: TANAKA RIYOUICHI
IPC: B60K17/10
Filed: 1978-03-06
Abstract: PURPOSE: To prevent the supply fluid to motors of a self-travelling vehicle from escaping thereform by opening an escaping circuit from the downstream side of a balance valve only when the valve is closed in a pilot pressure mechanism for operating a gear shifting valve upon increase of supply pressure to the two motors of the vehicle.  
     CONSTITUTION: When supply pressure to motors M 1 , M 2  of a self-travelling vehicle is increased, a balance valve 13 is opened against the urging pressure of a compression spring 11 to close an escaping circuit 14 and pilot pressure is applied to a gear shifting valve 7 to convert the second state for driving the motors M 1 , M 2  to the first state for driving the pumps P 1 , P 2  via the motors M 1 , M 2  by the joining fluid from the pumps P 1 , P 2 . When it is converted from the second to first states, the circuit 14 is closed so that the supply fluid to the motors M 1 , M 2  does not escape through the circuit 14 due to the pilot pressure so as to secure necessary running torque for the first state.

Title: Flow-staraightening duct
Inventor: NISHIJIMA SHIGEYUKI
IPC: G01M9/02
Filed: 1995-01-23
Abstract: PURPOSE: To greatly miniaturize an apparatus itself, reduce the setting area therefor and obtain a sufficient flow-straightening effect, by dividing the interior of an expanded duct by a plurality of partition plates, and setting the spreading angle of each divided duct to be not larger than an angle generating the detachment of the flow. CONSTITUTION: The spreading angle of a duct necessary for preventing the detachment of a flow from a wall surface of the duct and obtaining a flow straightening effect is set to be not larger than 7 deg.. When the duct is divided half by a partition plate 6, 14 deg. in total becomes allowable because each duct has a spreading angle of 7 deg.. The total length of an enlarged duct 3 can be reduced to 1/2. Similarly, if the duct is divided into three parts, the spreading angle becomes 21 deg. and the total length is approximately 1/3. If the duct is divided into four parts, the spreading angle is 28 deg. and the total length is reduced to about 1/4. In this manner, since the detachment of a flow is completely prevented, the total length of the enlarged duct 3 can be decreased remarkably.  Moreover, an increase of a pressure loss results only from a frictional loss by the partition plates 6, i.e., the loss is considerably small, not causing a problem.
