Abstract (en)
[origin: EP4191065A1] A pump (100) includes a body (102) defining an inlet (104) and an outlet (106). A first valve (300) selectively opens a backflow opening (110). The first valve (300) includes a first valve housing (306), such that a first valve body (308) is biasingly coupled by a first spring (310) within the first valve housing (306). The first valve body (308) moves the first spring (310) to a first compressed state, and to a first uncompressed state. A second valve (312) provided within the first valve (300) includes a second valve body (314). The second valve body (314) is biasingly coupled by a second spring (316) within the first valve body (308). The second valve body (314) moves the second spring (316) to a second compressed state to allow flow of the liquid, and to a second uncompressed state to disallow flow of the liquid through the second valve (312).
