Abstract: The invention relates to a chamber, in particular a pump chamber, comprising a plate-shaped first half (10) and a plate-shaped second half (12). The first and second halves are connected to one another by a closed connecting seam (20) in a surface-to-surface relation, and at least one half has at least one aperture (14) lying within the connecting seam. Furthermore, at least the second half is thermally deformed within the closed connecting seam in such a manner that it is formed to bulge relative to the connecting surface with the first half such that a hollow space (30) is formed between the first and second halves. In a second aspect, the invention relates to a pump having a configuration as described above. In a third aspect, the invention relates to a method for producing a chamber as described above.

Abstract: Although modern diesel fuel formulations are intended to reduce emissions of diesel engines, at least some of those modern fuels tend to have relatively low lubricity levels. The control valve assemblies described herein help to minimize any increased wear that would otherwise result from the use of such low lubricity fuels by providing a valve element, a valve guide, and an insert. The valve element is received within the valve guide and is moveable between an open position and a closed position. The insert forms a first sealed interface and a second sealed interface with the valve element and the valve guide. When the valve element is in the closed position, both of the first sealed interface and the second sealed interface are engaged. When the valve element is in the open position, only one of the first sealed interface and the second sealed interface is engaged.
