A pressure oil injector assembly characterized by novel features of construction and arrangement providing easy and quick mounting and dismounting and which has good transportability comprising an attachment and connecting member with connections for a pump housing of a pressure medium pump and a pressure pipe. The mounting arrangement is such that the high pressure side of the pump in in communication with the pressure pipe. The pump housing and pressure pipe are connected to the attachment and connecting member by means of threaded dowels which seat in threaded bores in the attachment and connecting member which are opposed to each other and spaced by a chamber or aperture. In the principal embodiment, a manometer seats in the aperture with a certain amount of play and is supported in a firm position between the inner terminal ends of the dowels. Accordingly, the angular position of one of the dowels and therefore, also the angular position of the pump can be freely chosen in relation to the attachment and connecting member and the parts including the manometer can be firmly connected in a leakproof manner simply by tightening the other dowel.
A pressure oil injector assembly comprising an attachment and connecting member (4) having connecting means for a pump housing of a pressure medium pump (1) and a pressure pipe (6), the high pressure part of the pump being in communication with the pressure pipe, means for connecting the pump housing and the pressure pipe to the attachment and connecting member including threaded dowels (3, 5) which engage in threaded bores in said attachment and connecting member, said bores being opposed to each other, an insertable member adapted to seat in an aperture in said attachment and connecting member located between said threaded bores, said dowels adapted to be threaded toward one another in said bores to lock said insertable member therebetween, said threaded bores being arranged in a predetermined manner so that said one dowel connected to said pump may be selectively positioned in a predetermined angular position when the dowels lock said insertable member therebetween whereby the angular position of the pump can be selectively chosen in relation to said attachment and connecting member.
