The suction relief valve has a tubular section (10) with an opening (21) on the low pressure side, and an opening (23) on the inflow side. The tubular section is contained in a housing (12) subjected to pressure in an axial direction. The section has an eccentric line- or strip-shaped part (16,18) at right angles to the longitudinal axis (14) to compress it to form a seal. The tubular section in a longitudinal and sealing position consists of two equilateral triangles (24,26) of different heights with a shared apex. |
