Patent ID: 7661873

Claim:
A homogeniser for continuous treatment of fluids at very high pressure, comprising: at least one single-acting plunger with reciprocating motion from a guide chamber to a compression chamber from a fluid intake position to a fluid delivery position; a plunger block for each said plunger, connecting the compression chamber with at least one intake valve and with at least one delivery valve for each said plunger; an internal manifold connecting the compression chamber with the at least one intake valve and the at least one delivery valve; at least one intake pipe and at least one delivery pipe both communicating with the manifold and respectively terminating in the intake valve and in the delivery valve, wherein the at least one intake valve and the at least one delivery valve are housed in separate containers fixed to the plunger block, and the homogeniser comprises at least one of the following units: a first, dynamic seal unit positioned around the guide chamber and in contact with a surface of the plunger, designed to create a seal on the plunger during compression; a second, static seal unit located close to an intersection between the compression chamber and the guide chamber, designed to contain pressure generated during compression between opposite surfaces of a compression chamber block and a housing flange for a dynamic seal; a third, static seal unit located upstream and downstream of each said at least one intake valve and said at least one delivery valve and at an intersection between the manifold and the compression chamber, respectively housed in hollows designed to prevent fluid from escaping.
