CONSTITUTION:During the compression stroke, with the hydraulic pressure increased by the advance of a piston 4, the hydraulic pressure in an upper chamber 9 is increased through an orifice  (not shown), the increased hydraulic pressure acts on a film coat 14 through an orifice 13, a gas  chamber 16 is compressed, an amount of the oil corresponding to the compressive deformation  escapes into the clearance between the film coat 14 and the inner cylinder wall 2a, to obtain a low  initial-stage damping force and provide an antivibration effect against the small ruggedness of the  road surface. When the stroke further grows larger, the hydraulic pressure in the chamber 9 becomes equal to the sum of the maximum pressure in the gas chamber 16 and the elastic force of  the film coat, a bottom valve 11 operates, and the hydraulic oil flows out into a chamber 8 to generate the rated damping force. During the extended stroke, the hydraulic oil is inclined to flow out  of the chamber 9, whereby the hydraulic pressure is increased and the valve of the piston 4 is opened, and the oil flows out into a lower chamber 10 through the orifice.

Title: Shifting control device for automatic transmission
Inventor: SATO OSAMU
IPC: F16H61/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To restrain a shift shock due to overshoot of signal pressure by interposing an orifice restraining shift shock due to variation of signal pressure between an accumulator valve and an actuator. SOLUTION: When line pressure PL from a shift valve flows in a line pressure circuit 20 for performing shifting, while working oil is charged into a hydraulic circuit from an accumulator valve to a band brake servo 2, a passing flow at an orifice 3 is enlarged, and differential pressure ΔP is generated across the orifice 3. Hereby, during the charging term of working oil, output pressure P1 is higher than feed pressure P2, and build-up of the feed pressure P2 is relatively delayed to the output pressure P1. Overshoot of accumulator control pressure Pa acting on the accumulator valve as signal pressure is generated before the build-up of the feed pressure P2, because it is generated directly after beginning of shifting. Consequently, overshoot of the feed pressure P2 can be prevented from generating, and shifting can be smoothly controlled.

SOLUTION: While the first elevating means 12 are shrunk, an under carriage 10 is lifted by means of the second elevating means 14 on the right sides and the left sides in the front part and in the rear part. While the under carriage 10 is kept lifted, extension means 13 on the left side and on the right side in the front part are shrunk, and at the same time, extension means 13 on the left side and on the right side in the rear part are extended synchronously with this shrinking action, so that the vehicle body 10 is advanced, and a vehicle body 11 and the first elevating means 12 positioned on the left side and on the right side in the rear part of the vehicle body 11 are positioned in front of an obstacle 4.  After the first elevating means 12 are extended so as to be landed while the second elevating means 14 are shrunk, the extension means 13 on the left side and on the right side in the rear part are shrunk, and subsequently, the first elevating means 12 is shrunk, so that the vehicle body 10 is landed. In this way, the vehicle can climb over the obstacle by itself and is moved easily.
