Abstract: In some embodiments, a composition of matter includes aripiprazole, a metal selected from the group consisting of magnesium, zinc, sodium, lithium, iron, or alloys thereof, or combinations thereof and a copper salt selected from the group consisting of copper iodide, copper chloride, copper bromide, copper sulfate, copper formate, or combinations thereof.

Abstract: Known pressure regulating valves have a valve closing body, which cooperates with a valve seat, and a restoring spring, which acts on a valve closing body in the direction facing away from the valve seat. It is disadvantageous that the restoring spring is disposed in a pressure chamber, which has the valve seat and through which aggressive blowby gases flow out of the crankcase. The blowby gases for instance have a corrosive, etching effect on the material of the restoring spring, shortening the service life and lessening the spring force of the restoring spring. This has a highly adverse effect on the regulation of the pressure in the crankcase. In the pressure regulating valve of the invention, the service life of the restoring spring is increased. According to the invention, the restoring spring (31) is embodied as a tension spring and is located on the side of the valve closing body (15) facing away from the valve seat (12).

Abstract: Known pressure-regulating valves, in particular, from the crank housing exhaust, have a regulating membrane made from an elastomer or a plastic. Elastomers, however, have a high permeability for hydrocarbons, an unsatisfactory chemical durability relative to oil, fuel and fuel additives and poor elasticity with low temperatures. Thermoplasts do not have these disadvantages and are better suited as materials for a regulating membrane. According to the present invention, it is proposed to use a membrane made from metal, preferably stainless steel. The membrane has a corrugated or graduated form. The pressure-regulating valve of the present invention has good characteristics with reference to permeability for hydrocarbons, chemical durability and temperature dependence of the elasticity and is substantially simplified through functional integration. The membrane assumes additionally the functions of a restoring spring and a housing cover.
