摘要： The pump has a tappet (3) axially guided into a guide borehole (2) of a pump housing (1), and a security element (4) for preventing rotation of the tappet around a longitudinal axis. The security element is inserted into a recess (5) of the borehole such that the security element stands in engagement with an external-sided guide groove (6) arranged at the tappet. The security element has parts (4.1, 4.2) for fixing a position in the recess of the borehole and/or for securing the position. The parts are movable opposite to each other along correspondingly shaped wedge- or cone surfaces.

摘要： The invention relates to a housing part, in particular a pump housing part, having a metering unit fastened in a pressure-tight manner to the housing part so as to be detachable, that is to say separable repeatedly without destruction. In order to optimize the fastening of the functional part, a collar is provided on the housing part, the collar having a tapered collar face against which a first tapered face of at least one tapered element bears, the tapered element having a second tapered face with which a tapered ring face of a tapered ring comes into contact when the tapered ring is moved from an open position into a closed position in order to press a positively locking face of the tapered element against a mating face which is provided on the functional unit.

摘要： The valve (36) has a valve unit to cooperate with a valve seat arranged in a valve housing. The valve unit is acted upon by a valve spring in a closing direction and by pressure predominant at a low-pressure area in an opening direction. A compensating piston is movably arranged in the housing and acted upon by pressures predominant in the low pressure area and a discharging area. The piston performs a stroke movement independent of the valve unit corresponding to a difference in pressures acting on the piston, when the valve unit is in a closed position.

摘要： The pump has a pump housing (10) and a drive shaft (12) for moving a pump element (20). The shaft is rotatably supported in the housing by bearing areas (11a, 11b) formed as sliding bearings. The bearing areas are formed by recesses (40a, 40b) in the housing. The housing has a main housing (14) and a flange (15) made of aluminum or aluminum alloy, which is converted into a layer of alumina ceramic in an area of a surface at the bearing areas. Components arranged in the housing are converted into oxide ceramic which is formed from Keronite(RTM: Electrolytic surface treatment).

摘要： The valve has a valve support, an inlet, an outlet, a valve element and a valve spring. The valve element is formed as the valve disc and functions with a pipe bracket side or bevel hub. The inlet and the outlet are arranged coaxially with each other. The valve support and the valve disc, are made as sheet metal molded part. The valve disc has an axially running collar, which guides the valve disc in the valve support. The valve disc has a sealing area, which functions with the bevel hub, where an opening lies radially outside the sealing area.
