摘要： Medical pumps for water jet surgery are known. The invention relates to a pump comprising at least two pistons provided with piston rods for displacing the pistons in cylinders and for coupling to a pump actuation device, a cylinder head for closing the cylinders, and valve means for respectively connecting a pressure chamber in the cylinder to at least one fluid inlet and at least one fluid outlet. Said fluid outlet is connected to the fluid inlet in a communicating manner by means of an adjustable pressure regulating valve, in such a way that the pressure in the fluid outlet can be limited to a predetermined maximum value so that operation of the pump can be.

摘要： A pressure enclosure includes a first component having an opening, a second component coupled to the first component in a position over the opening, a third component positioned between the first and second components and covering the opening, and a load chamber defined by a space between the second and third components and configured such that pressure in the load chamber biases the third component against the first component to seal the opening. The pressure enclosure may be a cylinder of a pump for pressurizing fluid or gas, with the first component a cylinder body, the second component an end cap and the third component a valve body, with the load chamber biasing the valve body against the cylinder body.

摘要： A sealing arrangement for a pump includes a first member having a peripheral wedge-shaped pocket; a second member with a rim opposed to the pocket; and a diaphragm disposed between the two members. The diaphragm includes a central stem, a disk-shaped head attached to the stem, and an upstanding bead disposed around the periphery of the head. The bead includes a first angled surface and a second angled surface. The bead is received in the pocket so as to form two separate, spaced-apart sealing surfaces between the diaphragm and the first member. The sealing arrangement may also include a gasket made from a resilient material and having a flat web with a circular crosssection bead disposed in a gland between two members. The dimensions of the bead and the gland are selected such that the bead is diametrically compressed at least about 40% from its free state.

摘要： Y-block or right-angular fluid section plunger pump housings have cylinder, suction, discharge and/or access bores which are transversely elongated within transition areas for interface with other bores to provide internal access, stress relief and a reduction in housing weight. A two-piece suction valve spring retainer assembly further reduces stress near the bore interfaces and allows use of a top stem guided suction valve that may be installed without threads in the suction bore. Tapered cartridge packing assemblies facilitate use of a one-piece plunger and also allow packing in such housings to be changed without removing the plunger.

摘要： It is an object of the invention to, even in the case where liquid containing a sedimenting material such as slurry is used, prevent sedimenting and aggregation from occurring in a pump. As means for attaining the object, a bellows 7 that is extendingly and contractingly deformable in the axial direction is placed in a pump body 1 with setting the axis B of the bellows vertical so as to be driven to perform extending and contracting deformation, and form a liquid chamber 9 inside the bellows 7. A suction port 18 and a discharge port 19 are formed in an inner bottom face 4a of the pump body 1 facing the liquid chamber 9. Liquid is sucked from the suction port 18 into the liquid chamber 9 by extension of the bellows 7, and the liquid in the liquid chamber 9 is discharged from the discharge port 19 by contraction of the bellows 7. The inner bottom face 4a is formed into a conical shape in which the face is downward inclined as moving toward the discharge port 19. Therefore, also liquid containing a sedimenting material such as slurry can be always smoothly discharged toward the discharge port 19 along the downward inclined face of the inner bottom face 4a without collecting on the inner bottom face 4a of the liquid chamber.

摘要： A check valve assembly mounted on an end surface of a projection of a valve body. The check valve assembly includes a valve having a curved sealing surface disposed adjacent a fluid inlet intersecting the end surface of the projection. The check valve assembly further includes a rigid mounting plate having a cavity that receives and maintains the valve between the cavity and the fluid inlet. The curved surface of the valve partially extends into the fluid inlet and has a circular line of contact against the end surface of the projection around the fluid inlet to define a closed valve position. The valve is positioned away from the closed valve position to define an open valve position.

摘要： A high-pressure, plunger-type liquid pump including a liquid manifold that includes a plunger chamber in the form of an axial cylindrical bore portion for slidably receiving a pressurizing plunger, and that also includes a valve chamber coaxial with the plunger chamber and in communication therewith for removably receiving a cartridge-type flow control valve. The liquid manifold includes a closure plug to close the valve chamber. The cartridge-type valve is slidably received in the valve chamber for enabling removal of the cartridge-type valve from the liquid manifold without the need for separating the liquid manifold from the pump drive housing. The cartridge-type valve is of a structure that includes in-line, axially spaced suction and discharge valves that are each spring biased into closed positions. High-pressure liquid is confined within a valve housing body that contains the suction and discharge valves, to minimize damage to the liquid manifold as a result of pressure fluctuations and high-pressure flows. The cartridge-type valve is removable from the manifold without the necessity of removing or even separating the manifold from the pump drive housing.
