20110271670 | MOTOR-PUMP ASSEMBLY - Disclosed is a motor-pump assembly ( | 11-10-2011 |
20110277464 | Motor-Pump Assembly - Disclosed is a motor-pump assembly ( | 11-17-2011 |
20120269664 | MOTOR-PUMP UNIT - A motor-pump unit, for providing pressure for a brake actuating device having a pneumatic brake booster including a pump and an electric motor driving the pump, the pump being a dual diaphragm pump having two opposed working diaphragms, each of which is clamped between a pump casing and a working chamber cover and delimits a working chamber, and moveable by a crank drive having connecting rods and bearings, the working diaphragm connected firmly to a tappet and, together with the connecting rod, in each case forming a diaphragm unit. In order to provide a low-noise motor-pump unit which is more cost-effective and requires reduced expenditure on assembly, the connecting rods are made of plastic, wherein in each case one tappet and one bearing are encapsulated with the material of the connecting rod. Alternatively, the connecting rods can be formed in one piece with the tappet and provided as sintered components. | 10-25-2012 |
20130213033 | MASTER CYLINDER FOR A REGULATED BRAKING SYSTEM - A master cylinder for a regulated braking system having at least one piston, which is movable in a housing and which is sealed from a pressure chamber by a sealing element arranged in a ring groove of the housing, which can be connected to an unpressurized supply chamber by control passages designed in the pistons. In order to reduce the flow resistance of the control passages at the same dead stroke, the control passages have a control edge designed parallel to a piston end face of at least one of the pistons. | 08-22-2013 |
20150030476 | PUMP UNIT DRIVEN BY AN ELECTRIC MOTOR - The invention relates to a pump unit that can be driven by an electric motor, in particular for providing vacuum for a pneumatic brake booster, including a pump housing that can be closed by a working-chamber cover and at least one elastic displacement element, wherein a working chamber is bounded between the displacement element and the working-chamber cover and wherein inlet valves and outlet valves and inlet channels and outlet channels associated with the valves are associated with the working chamber. According to the invention, in order to reduce noise emissions, devices for reducing a contact surface between the working-chamber cover and the pump housing are provided. | 01-29-2015 |

20130090410 | Intumescent Fireproofing Systems and Methods - Water-based intumescent fireproofing formulations are provided that exhibit excellent fireproofing properties while simultaneously significantly reducing and/or eliminating the potential for VOC release and exhibiting excellent hangability properties. The intumescent fireproofing formulation includes a coalescent that significantly reduces and/or eliminates the potential for VOC release and fiber constituents, e.g., fibers of greater than 0.2 mm in length. Exemplary coalescents have a boiling point of at least 180° C. and include bis(2-ethylhexanoate) triethyleneglycol and 2,2,4-trimethyl-1,3-pentanediolmono(2-methylproponate). Intumescent fireproofing formulations are also provided that include clay to further improve performance. | 04-11-2013 |
