20110041936 | METERING UNIT - A highly precise and extremely compact metering unit for fluid media has a pump, two valves, and a fluid communication base with two ports, pump and valve channels, and a pump chamber. The pump is mounted on the pump chamber. The pump channels communicate with the pump chamber and the valves. The valve channels communicate with the valves and the ports. The pump and the two valves are arranged one beside the other on the same side of the fluid communication base. | 02-24-2011 |
20130277398 | PNEUMATIC DOSING UNIT AND PNEUMATIC DOSING SYSTEM - A pneumatic dosing unit includes a housing having a first housing part for a pump-fluid receiving pump channel and a second housing part for dosing-fluid receiving channels. A cavity is formed between the housing parts. A flexible diaphragm is clamped between the housing parts and divides the cavity into a pump chamber and a dosing chamber that are fluidically separated from each other. At least one feed channel and at least one drain channel in the second housing part lead to the dosing chamber and start from the dosing chamber, respectively. Diaphragm valves in the feed channel and in the drain channel are spaced apart from the pump chamber and the dosing chamber and are controllable via control channels in the first housing part. The diaphragm and the diaphragm valves are arranged in such a way that dosing fluid does not come into contact with the first housing part. | 10-24-2013 |
20140251450 | METERING SYSTEM, HOUSING PART FOR A METERING UNIT AND METERING UNIT - A metering system for metering a metering fluid includes at least one metering unit, a fluid supply component conveying the metering fluid to the metering unit, and a control module conveying a control fluid to the metering unit. The metering unit includes a first housing part, an exchangeable second housing part and a membrane which is arranged between the housing parts and divides a cavity formed between the housing parts into a pumping chamber and a metering chamber which are separated from each other in fluidic terms. Channels are formed in the first housing part which receive the control fluid and are in flow connection with the control module, and channels are formed in the second housing part which receive the metering fluid and are in flow connection with the fluid supply component. | 09-11-2014 |

20120282078 | BEARING ASSEMBLY WITH DAMPING FEATURES - A turbocharger bearing assembly can include a compressor side bearing; a turbine side bearing; and a spacer configured to axially space the compressor side bearing and the turbine side bearing where the spacer includes lubricant passages to direct lubricant to spacer-bearing interfaces and where the spacer optionally includes a spring disposed in a central through bore to load the bearings. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed. | 11-08-2012 |
20140069094 | OUTER RACE LOCATING WASHER - An assembly for a turbocharger can include a locating washer having an axis and a perimeter that includes a chord segment defined by an apothem measured from the axis; a bearing assembly that includes an outer race having an axis and a perimeter that includes a chord segment defined by an apothem measured from the axis; and a housing that includes a bore for receipt of the bearing assembly and a recess for receipt of the locating washer to space apart the axes of the locating washer and the outer race by a distance greater than the sum of the apothems that provides for contact between the chord segments upon rotation of at least one of the locating washer in the recess and the outer race in the bore. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed. | 03-13-2014 |
20140369865 | ASSEMBLY WITH BEARINGS AND SPACER - A method can include providing a turbocharger housing that includes a bore; providing a spacer; providing a shaft and wheel assembly with a first rolling element bearing assembly seated on a first portion of a shaft of the shaft and wheel assembly; providing a second rolling element bearing assembly; interference-fitting the spacer into the bore; inserting a free end of the shaft into the bore and through the spacer; and inserting the second rolling element bearing assembly into the bore and seating the second rolling element bearing assembly on a second portion of the shaft such that the spacer is disposed intermediate the first portion of the shaft and the second portion of the shaft. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed. | 12-18-2014 |
