摘要： A check valve (1) is described, the check valve (1) including a valve housing having a first port (2) and a second port (3) connected to a valve chamber (4), a valve seat (5) having a valve seat axis (6) and being arranged between the first port (2) and the valve chamber (4), and a valve element (7) movably arranged within the valve chamber (4) between the valve seat (5) and a stop face (8) opposite the valve seat (5), wherein the valve housing includes a first part (9) having the first port (2) and a second part (10) having the second port (3) and being connected to the first part (9). Such a check valve should have a simple design. To this end the second port (3) opens into the stop face (8) by means of an array of holes (12), wherein the cross section area of the holes (12) is smaller than the smallest cross section area of the valve element (7).
