Zusammenfassung:	A positive displacement pump includes a drive chamber and a housing covering a diaphragm compartment. A drive element is inside the drive chamber. A diaphragm is inside the diaphragm compartment, and divides the diaphragm compartment into a fluid chamber and a cavity. A shaft connects the drive element and the diaphragm. A breather valve is fluidically connected to the cavity, and is configured to allow air to be discharged from the cavity. The cavity is fluidically separated from the drive chamber. 정변위 펌프는 구동 챔버 및 다이어프램 격실을 둘러싸는 하우징을 포함한다. 구동 요소는 구동 챔버 내측에 있다. 다이어프램은 다이어프램 격실 내측에 있고, 다이어프램 격실을 유체 챔버 및 캐비티로 분할한다. 샤프트는 구동 요소 및 다이어프램을 연결한다. 브리더 밸브는 캐비티에 유체적으로 연결되고, 공기가 캐비티를 빠져나가는 것을 허용하도록 구성된다. 캐비티는 구동 챔버로부터 유체적으로 분리된다.
