Abstract: PROBLEM TO BE SOLVED: To assure the safety of operation by an inexpensive device by communicating cylinder spaces on a piston of each cylinder device to each other and providing an added valve device as an electrically operating valve common to each cylinder device in a coupe type car in which a foldable roof is opened and closed by a plurality of cylinder devices. SOLUTION: In a liquid circuit comprising a cylinder device (a) for locking a bar for a storage space storing a foldable roof and three sets of cylinder devices A to C for opening and closing a cover in order, spaces under pistons of the cylinder devices A to C are connected to a pressure conduit through electric control valves 11a and 11A to 11C and a check valve 13a and 13A to 13C, respectively. Also the spaces above the pistons are communicated to each other, and connected to the pressure conduit through added common solenoid valve 12 and check valve 14. Then, the valves 11a, 11A to 11C, and 12 are controlled drivingly by an electric control circuit together with the driving motor of a pump 8 according to a roof opening and closing sequence.

Abstract: PURPOSE: To prevent undesired rising of an object due to the decrease of load by exposing the largest and smallest end surfaces of a spool member to the pressure of a branch conduit and exposing the differential surface to the pressure of a return conduit. CONSTITUTION: A multi-pilot-operated check valve 21 is attached at a branch conduit 14. The largest operation surface of a differential spool 22 is exposed to the pressure inside the branch conduit 14 by way of a pilot control conduit 14', and the smallest surface is also exposed to the pressure inside the branch conduit 14. The spool 22 is moved to the left by the pressure supplied to the ring-shaped spool surface between the largest surface and the smallest surface of the spool 22 by way of the pilot control conduit 24 together with the pressure imposed on the smallest spool surface, and a check valve 23 is closed. Even if the piston load is reduced, the supported part will not make undesirable movement since the check valve 23 is closed and liquid is not supplied from an accumulator 15.

Abstract: PROBLEM TO BE SOLVED: To absorb energy of time cycle vibration of a structural member by providing a first spring and a second spring which include rings provided with rods connected between the rings and have the stiffness which determines resonance frequency at which a first barrel part and a second barrel part vibrate. SOLUTION: A first deflection body 36 has circular rings 37 and 38. A rod 40 is thin between the rings 37 and 38 and a diameter of a cross section thereof is small at a central position thereof so that the first deflection body 36 plays the role of a spring. A second deflection body 55 is formed by a rod 59 having a circular cross section and rings 57 and 58. A retaining ring 51 enters an end part of a housing and comes in contact with the ring 58 of the second deflecting body 55. By changing the stress which acts on the rods 40 and 59 of a deflecting body assembly, the stiffness of the spring is changed to change resonance frequency and to adjust a vibration absorbing device. Consequently, the vibration energy can be absorbed by the vibration of a durable mass body 32 and a motor assembly 50 in the optimum condition.

Abstract: PROBLEM TO BE SOLVED: To form the parts of a safety device with a low strength material by arranging the safety member near a fixed portion and stretching a projection member in the groove of the fixed portion through the opening of the safety member at the locking position time of a piston cylinder assembly. SOLUTION: A fixed portion 6 is arranged near a safety member 1 and at the stretching time of a piston rod, the safety member 1 slides under a projection member 8 and bracket 7 and the projection member 8 is pushed into the opening 2 by a twist spring pressure and into the groove 13 of the fixed portion 6 during passing the opening 2 of the safety member 1. When the piston rod is further stretched, the projection member 8 is pushed up to the rear side of the opening 2 and inclined on the safety member 1. When the piston rod is pulled in, the projection member 8 is pushed in the groove 13 through the opening 2 and when the piston rod is further pulled in, the surface 14 of the safety member 1 is contacted to the projection member 8 and run and the safety member 1 is fixed to the fixed portion 6. By above constitution, even an inexpensive material with a low strength can work as the safety device surely.

Abstract: PURPOSE: To provide a plunger pump rationalized in arrangement of a reservoir, an electric motor and the like, and in a production cost. CONSTITUTION: A radial plunger pump 1 has a pump housing 2 provided with radial cylinders 6 within it, and a plunger 7 for reciprocating in each the cylinder 6 through an eccentric rotor 11. The pump assembly integrally comprises the radial plunger pump 1, an electric motor 40 for driving the rotor 11 of the radial plunger pump 1, and a reservoir main body 20 for hydraulic oil.

Abstract: The vehicle 1 is intended for positioning a patient within a nuclear magnetic resonance machine 2. A base 59 on wheels 9 supports a carriage 7 which can be raised by a hydraulic cylinder. The patent lies on a cradle 8 which slides longitudinally on the carriage 7. A housing 5 on the machine 2 encloses a hydraulic motor which is coupled to drive a hydraulic pump on the vehicle 1 when the latter is wheeled into position. Portion 5a of the housing 5 is tapered to guide the vehicle into the correct position and incorporates a latching mechanism. … The hydraulic system on the vehicle has interlocks to ensure that the carriage can be lowered and the vehicle undocked only when the cradle has been retracted onto the carriage. Also the cradle is locked unless the carriage is at the correct height.
