    Abstract: Proposed is a pressure valve fitted in the feed line (7, 7') leading from a fuel-injection pump to a fuel-injection valve (8). The pressure valve has a closure element (121) which opens in the fuel-feed direction and which has a return-flow shoulder (135). To ensure uniform injection, in particular at a given load over the engine-speed range, the rate of increase of the cross-sectional area of the flow passage defined by the valve closure element (121) is controlled by virtue of the fact that, immediately adjacent to the return-flow shoulder (135), is a control element (131) with three recesses (138) round its perimeter. These recesses are bounded by the through-channel (120) in which the valve-closure element (121) is guided, and have the same, given, opening area, the sum of the opening areas being of the same order of magnitude as the cross-sectional area of the feed line. As the stroke movement progresses, the rim (139) bounding the recesses (138) on the flow-return shoulder (135) and the rim (122) at the outlet of the through-channel (120) together leave in the zone of the recesses (138) a complete passage which is never larger in cross-section area than the cross-sectional area of one recess.

    Abstract: A check valve comprising a poppet urged by a conical spring to annularly seal uniformly around its entire periphery to assure more uniform cracking pressure about its entire periphery. The cracking pressure may be adjusted by means of an adjustable plate which reduces the length of the conical spring and thereby increase the amount of force exerted by the spring onto the poppet into sealing engagement, thereby increasing the cracking pressure.

    Abstract: A positive displacement pump (50) includes a relief valve comprising a valve seat (61), a needle (62) within the valve seat, a spring (63) forcing the needle within the valve seat, a set screw (65) pressing the spring against the needle and a spacer (64) for mounting the set screw to the housing of the positive displacement pump. The valve seat threadably connects within the relief valve passageway to prevent the erosion of the passageway. The valve seat may be constructed from a plastic, hard rubber, or metal material and include a rubberized seal secured at one end of the valve seat. When the valve seat erodes to a point where it provides an insufficient seat for the needle, it is removed from within the relief valve passageway and replaced with a similar valve seat. By protecting the relief valve passageway from erosion by using an inexpensive, removable, and disposable valve seat, costly disposal or machining of the housing of the positive displacement pump is avoided.

    Abstract: A delivery valve is incorporated into the delivery pipe (7, 7') that leads from a fuel injection pump to a fuel injection valve (8) and has a valve closure member (21) that opens in the fuel delivery direction and is provided with a recirculating collar (35). In order to achieve uniform injection, in particular a uniform injection curve, over the rotation speed range, the opening rate of the connecting cross-section at the valve closure member (21) is controlled by a control collar of same diameter (36) as the recirculating collar (35), arranged immediately adjacent the latter and having a recess (38) in its circumference that is delimited by a through-channel (20) for guiding the valve closure member (21) that has a defined open cross-section in particular of the same order of dimension as the cross-section of the delivery pipe. An outlet edge (22) of the through-channel (2) cooperates with the control collar (36) and liberates with an increase in stroke a connecting cross-section of the recess (38), which however never becomes larger than the open cross-section.
