摘要： The fluid pump has a casing defining an inlet manifold, an outlet manifold and a plurality of piston chambers between the inlet manifold and the outlet manifold, each piston chamber having a piston therein for drawing fluid into the piston chamber from the inlet manifold and for pumping fluid out of the piston chamber into the outlet manifold, and a spring biased check valve associated with each piston chamber wherein a spring biases each valve toward the piston chamber and seals the piston chamber from the outlet manifold, the improvement comprises: at least one of the check valves having a hole therethrough which provides open communication between the outlet manifold and the piston chamber, blocking and sealing structure associated with the check valve for blocking and sealing the opening, and a mechanism for moving the blocking and sealing structure between a first position wherein the hole is blocked and sealed and a second position whereby the hole is not blocked or sealed, such that when the blocking and sealing structure is in the first position, liquid is prevented from flowing from the outlet manifold back into the piston cylinder and thereby causes fluid to exit the pump in a continuous flow and when the blocking and sealing structure is in the second position fluid can flow from the outlet manifold into the piston cylinder and fluid exits the pump in a pulsed or vibratory flow.

摘要： The suction and force plunger pump has at least one pumping chamber (31) in which a suction and force plunger (18), actuated by a cross-head crank system (14), is inserted at a packing-gland sealing device (32, 33). While said plunger is connected to said cross-head by means of a quick coupling (19), the packing-gland device is mounted so as to be extractable from said pumping chamber through an opening (23) thereof opposite to said cross-head and, at the same opening, its casing (35) is axially but not tangentially engaged by a ring (37) which is normally adapted to ensure the sealing lock between said chamber (31), said casing (35) and said ring (37) and vice versa to determine the extraction of the packing-gland device and, if said coupling is open, of the related plunger.

摘要： A pump assembly with valve-seat interface architecture configured to extend the life of pump components and the assembly. A valve (100) of the pump assembly is equipped with a conformable valve insert (101) that is configured with a circumferential component having the capacity to. reduce the radial strain' of its own deformation upon its striking of a valve seat at the interface within the pump assembly. The circumferential component may include a concave surface (150) about the insert, a rounded abutment (175) at the strike surface of the insert, or a core mechanism (200) within the insert that is of greater energy absorbing character than surrounding material of the insert. Additionally, the valve seat itself may be configured for more even wear over time and equipped with a conformable seat insert to reduce wear on the valve insert.

摘要： A double acting pump having inlet and outlet poppet valves clamped to the pump housing in proximity to an inlet manifold and an outlet manifold. The end portion of each cylinder in the double acting pump is provided with a sloped wall to prevent debris in the pumped fluid from becoming stuck in the pump cylinder. Each poppet includes a valve housing having a spring biased valve head slidably mounted therein and engageable with a removable valve seat. A stem is connected to the valve head and extends through an end wall of the valve housing to the exterior thereof to function as an external indicator rod to indicate the position of the valve head within the valve body. A handle is connected to the stem so that the stem can be manually pulled to lift the valve head from the seat to check the operation of the poppet valve, and a disc is mounted on the stem a predetermined distance from the end wall when the valve is in the closed position so that the wear between the valve seat and head can be obtained. The valve seat is dimensioned to allow a substantially unrestricted flow of fluid therethrough and having a 45.degree. slope engageable by a 90.degree. edge on the valve head to minimize the surface area between the valve head and seat so that debris cannot be trapped between the valve head and seat to prevent the valve head from properly seating.
摘要翻译：双作用泵具有入口和出口提升阀，其夹持在靠近入口歧管和出口歧管的泵壳体上。双作用泵中的每个气缸的端部设置有倾斜的壁，以防止泵送的流体中的碎屑粘附在泵气缸中。每个提升阀包括具有可滑动地安装在其中并可与可移除阀座接合的弹簧偏压阀头的阀壳体。杆连接到阀头并且延伸穿过阀壳体的端壁到其外部，用作外部指示器杆以指示阀头在阀体内的位置。手柄连接到阀杆，使得阀杆可以被手动拉动以将阀头从阀座抬起以检查提升阀的操作，并且当阀门与阀门预定距离时，阀杆安装在距离端壁预定距离处处于关闭位置，从而可以获得阀座和头部之间的磨损。阀座的尺寸设计为允许流体通过其中基本上不受限制的流动并且具有可在阀头上接合90°边缘的45°斜率，以使阀头和阀座之间的表面积最小化，使得碎片不能被捕获在阀头部和座椅，以防止阀头正确就位。
