Claim:
1. A pressure-sensitive damper, comprising: a first cylinder at least partially defining a first fluid chamber, said first fluid chamber containing a damping fluid; a damping piston for reciprocal motion within said first cylinder; a piston rod comprising: a second cylinder at least partially defining a second fluid chamber in fluid communication with said first cylinder; a compression damping plate fixed in said second cylinder; at least one passage in said compression damping plate through which said damping fluid, which is displaced by a movement of said piston rod, flows in a first direction from said first fluid chamber to said second fluid chamber to achieve a first fluid flow; a first pressure source in communication with said second fluid chamber; a valve for generating a resistance force to said first fluid flow, wherein said resistance force varies according to an amount of force communicated to said valve by said first pressure source, wherein said valve comprises: an intensifier piston comprising: a second pressure source acting on said intensifier piston, said second pressure source adapted to generate a second force tending to counteract an amount of said first force communicated to said valve by said first pressure source.
