摘要:
A compressor, in particular for air conditioning systems in motor vehicles, having a housing, a housing sealing cover, a drive shaft with bearings and a drive device for pistons that are displaced back and forth. The drive device transfers the rotational displacement of the drive shaft into the back-and-forth displacement of the pistons. The compressor also includes a cylinder block, in which the pistons that are displaced back and forth take in and compress coolant, a valve device, in addition to a valve plate with intake and discharge valves comprising intake and discharge chambers for an intake pressure zone and a discharge pressure zone. A cylinder head may be a separate element from the housing, in pot-shaped form, or the housing sealing cover. The intake and discharge chambers, the valve device, and the cylinder block may be situated in the closed side of the pot-shaped housing.

An apparatus for machining flat workpieces has at least two tool carriers mounted to machining heads that are drivable by at least a first drive unit. The tool carrier of one machining head is arranged such that it is movable in a shifting range (V1) along a first axis relative to the carrier unit. The tool carrier of a second machining head is arranged such that it is movable in a shifting area (V2) along the first axis relative to the carrier unit.

An elongated bar shaped housing contains an optical sensing apparatus with at least one light source to create a sensing beam and a deflecting arrangement which moves the sensing beam back and forth between the longitudinal ends of the housing. One of the walls of the housing has an output window extending in the longitudinal direction of the housing for the sensing beam and an input window parallel to the output window for the sensing beam reflected from a workpiece or its support. In the housing behind the input window there is a strip shaped light receiving arrangement with a plurality of optical sensors, as well as an evaluation unit connected to the light receiving arrangement to which the output signals of the light receiving arrangement are sent.

In a band grinding machine, especially well adapted for grinding wooden frames having transverse and longitudinal wooden pieces, a support table in the form of an endless belt transports the frames in an advancement direction, a transverse grinding assembly with a transversely moving grinding band extending over the width of the support table grinds the entire tops of frames, and two longitudinal grinding assemblies, located behind the transverse grinding assembly in the advancement direction, respectively grind the two longitudinal wooden pieces of each frame, with each longitudinal grinding assembly having a longitudinally moving grinding band with a width very small in comparison to the width of the table, and with at least one of the longitudinal grinding assemblies being adjustable transversely of the advancement direction to allow the spacing of the longitudinal grinding assemblies to be set to match the spacing of the longitudinal frame pieces.
摘要:
The invention relates to a process for forming hollow stepped shafts of cold-formable metal by internal high pressure with the following steps: provision of a tube outlet section and filling it with fluid; sealing at least the tube section to be widened; application of a suitable high internal pressure for widening the tube section; calibration of the workpiece by applying a high calibration pressure; maintenance of the calibration pressure while heading the tube along the longitudinal axis. Internal tools, also spring-loaded tools, are provided as supports in the tool.
