摘要： A valve seat for a valve assembly for a high-pressure fluid pump is disclosed. The valve assembly includes a valve body, and a valve seat fabricated of a first material. The valve seat has a generally a tubular body having an annular collar having an outer diameter surface extending beyond the outer diameter surface of the tubular body, and an annular insert fabricated of a second material more durable than the first material and affixed to form an inner diameter surface of the collar, the insert forming an annular sealing surface against which the valve body abuts when in a closed position. The insert forms an annular ledge edge at its inner diameter surface that is offset from the inner diameter surface of the tubular body to form an annular chamfered edge.

摘要： A fluid end assembly of a hydraulic fluid pump includes a housing having a first housing bore and a second housing bore offset axially from the first housing bore. A plate is fastened to the housing. The plate has a first plate bore axially aligned with the first housing bore and a second plate bore axially aligned with the second housing bore. A first removable valve cover closes the first housing bore and a second removable valve cover closes the second housing bore. A first retainer engages the first plate bore and abuts the first removable valve cover and a second retainer engages the second plate bore and abuts the second removable valve cover.

摘要： A plunger of a high-pressure pump is provided reciprocatably on an inner side of a cylinder. A holder disposed on an opposite side of the cylinder from a pressurizing chamber includes a large tubular portion that provides a predetermined space between the large tubular portion and an outer wall of the plunger, and a small tubular portion that is disposed on an opposite side of the large tubular portion from the cylinder. A pin inserted into a hole of the plunger at a position corresponding to the large tubular portion protrudes radially outward from the outer wall of the plunger and is accommodated in a space on an inner side of the large tubular portion.

摘要： The invention relates to a hydrostatic radial piston motor, in particular a hydrostatic radial piston motor for actuating a differential cylinder. According to the invention, the hydrostatic motor in radial piston configuration comprises a control stud in a housing, the hydrostatic motor having three hydraulic working connections. The first working connection can be connected to the piston-end of a differential cylinder, while the second working connection can be connected to the rod-end of the differential cylinder. Finally, the third working connection can be connected to a tank. Owing to this arrangement, the differential cylinder can be directly operated with the aid of a single hydrostatic motor, with it being possible to forgo interposing proportional or control valves.

摘要： An apparatus can include a housing, a plunger configured to reciprocate along an axis within the housing, and an internal fluid chamber disposed in the housing. A valve, having a valve base and a deformable seal, can also be included in the apparatus. The apparatus can further include a seat having an aperture therein. The valve is configured to move into and out of contact with the seat when the plunger reciprocates within the housing, based upon a fluid pressure in the internal flow chamber. In addition, an outer diameter of the deformable seal of the valve is less than an outer diameter of the seat.

摘要： The present invention relates to a piston pump for feeding a fluid, having a piston and a pressure chamber which is arranged between an inlet valve and an outlet valve. The inlet valve has a closing element, a spring element for restoring the closing element, and a holding device. The holding device has a holding region for holding and supporting the spring element and an integrally formed sealing region in order to seal the pressure chamber with respect to a low-pressure region of the piston pump. The sealing region is of annular design and has a parting gap which is closed in an installed state.
