[origin: WO2020182921A1] The invention relates to a valve assembly for a diaphragm pump, the valve assembly having an inlet side and an outlet side. A first outlet channel (23) leads from an inlet opening (24) arranged on the inlet side to an outlet opening (25) arranged on the outlet side, and a second outlet channel (26) leads from an inlet opening (27) arranged on the inlet side to an outlet opening (28) arranged on the outlet side. An inlet channel (30) has a first part (31) and a second part (32), the second part (32) having an outlet opening (33), which is arranged on the inlet side, and the first part (31) extending at an angle to the second part (32). An inlet valve body (40) is provided at the outlet opening (33) of the second part (32) of the inlet channel (30), and a first outlet valve body (41) is provided at the outlet opening (25) of the first outlet channel (23). The outlet opening (28) of the second outlet channel (26) is closed and opened either by a second outlet valve body or also by the first outlet valve body (41).
