摘要： A shock absorber is attached coaxially with a reciprocating rod driven by a reciprocating unit for absorbing an impact force without bending the reciprocating rod. The shock absorber has a hollow rod provided with a through hole. The hollow rod is mounted within an outer cylindrical body. An accommodating space is formed between the hollow rod and the outer cylindrical body. A spring force toward one end portion side of the hollow rod is applied to the outer cylindrical body by a compression coil spring. An annular piston provided in the hollow rod partitions the accommodating space into two liquid chambers. When the impact force is applied to the hollow rod, the liquid flows from one liquid chamber to another liquid chamber through a gap, whereby a resistance force is applied to the hollow rod.

摘要： A shock absorber with a possible minimum peak value of the impact acceleration during a collision. The shock absorber includes a tubular cylinder part with an opening at one end and the other end closed, a seal part configured to seal the internal space of this cylinder part at a part closer to this one end inside this cylinder part, fluid filled in the enclosed space formed by this seal part inside this cylinder part, a slidable piston part inside this enclosed space, and a rod part that slidably penetrates this seal part concentrically and is connected to this piston part at one end while projecting out to the other side. This cylinder part has a tapered inner surface inside this enclosed space, reducing its internal diameter from the one end to the other end, and the rate of this taper is within the range from 1/50 to 1/130.

摘要： A shock absorber is attached coaxially with a reciprocating rod driven by a reciprocating unit to prevent a bending moment from being applied to the reciprocating rod in absorbing an impact force. The shock absorber has a hollow rod provided with a through hole and an outer cylindrical body mounted outside the hollow rod so as to be movable axially relatively and attached to the reciprocating unit. An accommodating space is formed between the hollow rod and the outer cylindrical body. A spring force in a direction of being relatively directed to one end portion side of the hollow rod is applied to the outer cylindrical body by a compression coil spring. An annular piston for partitioning an accommodating space into two liquid chambers is provided in the hollow rod. When the impact force is applied to the hollow rod so as to be slid to the hollow rod, the liquid flows from one liquid chamber to another liquid chamber through a gap, whereby a resistance force is applied to the annular piston.

摘要： A flow path switching valve has an injection side portion formed with an injection chamber and an outer valve seating surface, and a discharge side portion provided with a partition member formed with an inner valve seating surface. A discharge control block communicating with a discharge chamber is formed with a control flow path which is increased and decreased in volume by a discharge rod. To fill the control flow path with grease, a valve element closes an inner flow path and opens an outer flow path. On the other hand, to discharge the grease in the control flow path to the discharge chamber, the valve element closes the outer flow path and opens the inner flow path. After being supplied to the control flow path, the grease is supplied to the discharge chamber.
