Abstract
A pressure exchanger with a valve system includes a cylinder barrel (1), two valve plates (2) and two port plates (3, 4), wherein the cylinder barrel (1) has at least one cylinder (7) which accommodates a piston (8). The objective is to provide a pressure exchanger with low wear and a low maintenance effort. This objective is solved by a pressure exchanger including a piston (8) braking system and that the piston (8) includes a pressure relief arrangement.
Claims12
A pressure exchanger with a valve system comprising a cylinder barrel, two valve plates and two port plates, wherein the cylinder barrel comprises at least one cylinder which accommodates a piston, wherein the pressure exchanger comprises a piston braking system and that the piston comprises a pressure relief arrangement, wherein the piston comprises two sides facing in a longitudinal direction of the cylinder, and wherein the pressure relief arrangement comprises at least temporarily a fluidic connection between the two sides of the piston.
A pressure exchanger with a valve system comprising a cylinder barrel, two valve plates and two port plates, wherein the cylinder barrel comprises at least one cylinder which accommodates a piston, wherein the pressure exchanger comprises a piston braking system and that the piston comprises a pressure relief arrangement, wherein the piston comprises two sides facing in a longitudinal direction of the cylinder, and wherein the pressure relief arrangement is configured to reduce excess pressure on one of the two sides of the piston through a fluidic connection between the two sides of the piston.
