PUMP AND METHOD FOR MANUFACTURING THE PUMP

摘要

The pump (1) comprises a chamber (2) having an inlet opening (22) and an outlet opening (21). The chamber (2) extends between a first main wall (30) and a second main wall (40). The first main wall (30) is a triangular bottom wall of a body (3). The second main wall (40) is a part of a triangular bottom wall of a tub (4). The body (3) is tiltable relative to the tub (4) so that the volume of the chamber (2) is variable. The pump (1) comprises an outlet valve for blocking the outlet opening (21) when the volume of the chamber (2) is increased and an inlet valve for blocking the inlet opening when the volume of the chamber (2) is reduced. The outlet valve is formed by a first portion (31) of the body (3). This first portion (31) of the body blocks the outlet opening when the body is urged against the outlet opening (21). The inlet valve is formed by a second portion (32) of the body (3). This second portion (32) of the body blocks the inlet opening when the body is urged against the outlet opening (21).
