Abstract:
1. A pressure-sensitive damper, comprising: a first cylinder at least partially defining a first fluid chamber containing a damping fluid; a damping piston for reciprocal motion within the first cylinder; a piston rod having a first end connected to the damping piston, and a second end extending through an end of the first cylinder; a second cylinder at least partially defining a second fluid chamber in fluid communication with the first cylinder; a compression damping plate fixed in the second cylinder; at least one passage in the compression damping plate through which the damping fluid, displaced by the piston rod, flows in a first direction from the first fluid chamber to the second fluid chamber; a first pressure source in communication with the second fluid chamber; a valve for generating a resistance force to the fluid flow, wherein the resistance force varies according to an amount of force communicated to the valve by the first pressure source, the valve comprising: an intensifier piston; wherein the first pressure source acts on a first end of the intensifier piston and generates an intensified pressure at a second end of the intensifier piston, wherein the intensified pressure is communicated to the blow-off piston to create a force urging the blow-off piston toward the first position and; a bypass circuit adapted to permit a flow of the damping fluid in the first direction through the compression damping plate without passing through the at least one passage.
