Abstract: A rear casing is disclosed for a spray gun that has a handle part and a gun barrel connected to the handle part. The rear casing can be removably and exhangeably attached to the rear side of a main body of the spray gun and has a first region designed as a handle casing and a second region designed as a covering casing for rear-side covering of a rear region of the gun barrel. At least one connection element is provided on the second region of the rear casing for optionally forming a removable connection to a part having, for this purpose, at least some portions with a design complementing that of said connection element. In particular, according to the invention, the entire rear casing, together with the at least one connection element, is designed as a monolithic plastic component, in particular a plastic injection moulded molded part.

Abstract: A dense-phase powder pump for conveying powder-type materials, in particular coating powder, includes at least one powder conveying chamber with a filter element that has at least regions thereof accommodated in a casing body and at least one pinch valve that is or can be connected to an end region of the powder conveying chamber. In particular, the pinch valve includes a valve element with at least regions that are sleeve-like, wherein the peripheral wall thereof can be squeezed together transverse to the valve element longitudinal axis in order to change the through-flow cross-section, and also includes a substantially tubular support structure, in which at least regions of the valve element are accommodated, wherein the support structure consists of multiple shell elements which are arranged one after another around the peripheral wall in the peripheral direction of the peripheral wall of the valve element, each having an arched cross-section, and which are placed on the outside of the valve element in a radial direction relative to the valve element longitudinal axis.
