  "textContent": "A fluid pump (10) includes a housing (18); an inlet passage (34); an outlet conduit (50); a pumping element (28) within the housing (18); and a check valve assembly (52). The check valve assembly (52) includes a valve stem (54) within the outlet conduit (50) such that a flow path is created radially between the outlet conduit (50) and the valve stem (54), the valve stem (54) moving along a check valve assembly axis (56) between a closed position and an open position. The flow path includes a first restriction (68) which increases velocity of fluid passing through the flow path; a first expansion (70), downstream of the first restriction (68), which decreases velocity of fluid passing through the flow path; a second restriction (72), downstream of the first expansion (70), which increases velocity of fluid passing through the flow path; and a second expansion (74), downstream of the second restriction (72), which decreases velocity of fluid passing through the flow path.",
