A press, for the reversible disassembling of car shock absorbers, comprising: - a pneumatic cylinder with a relative movable stem, associated with a valve for the inlet of compressed air and with a control pedal; - first clamping means with push arms, wherein said first clamping means comprise grooved supports carrying the push arms, wherein said grooved supports are hinged on the opposed ends of everted edges of a body of said first clamping means, and rotate on said ends, and wherein said push arms comprise fixing hooks, integral therewith, that may be fixed either to the upper coils of springs of car shock absorbers, or to the upper spring-carrying disks of said shock absorbers; - second clamping means (5") with push arms, wherein said second clamping means (5") comprise grooved supports carrying the push arms, wherein said grooved supports are hinged on the opposed ends of everted edges of a body of said second clamping means (5"), and rotate on said ends, and wherein said push arms comprise fixing hooks, integral therewith, that may be fixed either to the lower coils of springs of car shock absorbers, or to the lower spring-carrying disks of said shock absorbers; - adjusting means for adjusting the independent vertical inclination of the push arms of the first and second clamping means (5', 5"); wherein the press comprises: - a single fixing hook integral with the body of each of the first and second clamping means (5', 5"), which can be fixed either to the upper or to the lower coils of springs of shock absorbers for motorcars, or to the upper or lower spring-carrying disks of said shock absorbers; - adjusting means for adjusting the symmetrical horizontal opening of the push arms of the first and second clamping means (5', 5"), adapted to vary the horizontal opening thereof without ever changing the centre thereof; wherein said adjusting means are adapted to keep said fixing hooks (12, 13) constantly arranged at reciprocal angles of about 120°, to allow to evenly distribute the thrust exerted by said arms on the spring of the shock absorber fixed to said clamping means (5', 5") and to avoid the occurrence in said spring of lateral lying down that might impede the correct compression thereof, and wherein said adjusting means (15, 20) allow the application of said push arms onto springs and/or spring-carrying disks of car shock absorbers with different helicoidality, structural shape and dimensions. - a pneumatic cylinder with a relative movable stem, associated with a valve for the inlet of compressed air and with a control pedal; - first clamping means with push arms, wherein said first clamping means comprise grooved supports carrying the push arms, wherein said grooved supports are hinged on the opposed ends of everted edges of a body of said first clamping means, and rotate on said ends, and wherein said push arms comprise fixing hooks, integral therewith, that may be fixed either to the upper coils of springs of car shock absorbers, or to the upper spring-carrying disks of said shock absorbers; - second clamping means (5") with push arms, wherein said second clamping means (5") comprise grooved supports carrying the push arms, wherein said grooved supports are hinged on the opposed ends of everted edges of a body of said second clamping means (5"), and rotate on said ends, and wherein said push arms comprise fixing hooks, integral therewith, that may be fixed either to the lower coils of springs of car shock absorbers, or to the lower spring-carrying disks of said shock absorbers; - adjusting means for adjusting the independent vertical inclination of the push arms of the first and second clamping means (5', 5"); wherein the press comprises: - a single fixing hook integral with the body of each of the first and second clamping means (5', 5"), which can be fixed either to the upper or to the lower coils of springs of shock absorbers for motorcars, or to the upper or lower spring-carrying disks of said shock absorbers; - adjusting means for adjusting the symmetrical horizontal opening of the push arms of the first and second clamping means (5', 5"), adapted to vary the horizontal opening thereof without ever changing the centre thereof; - a single fixing hook integral with the body of each of the first and second clamping means (5', 5"), which can be fixed either to the upper or to the lower coils of springs of shock absorbers for motorcars, or to the upper or lower spring-carrying disks of said shock absorbers; - adjusting means for adjusting the symmetrical horizontal opening of the push arms of the first and second clamping means (5', 5"), adapted to vary the horizontal opening thereof without ever changing the centre thereof;
