  • Publication number: 20230382711
    Abstract: The invention relates to a quick-change device for a filling adapter for filling vehicles on assembly lines in the automotive industry, on which circuits and containers of the vehicles are filled with operating materials which, starting from a filling system, are fed into the respective circuits and containers via hose assemblies with pneumatic and hydraulic lines and a filling adapter, wherein a separate connection plate is arranged at the separation point of the hose assembly from the filling system, and wherein a connection block is designed as a functional counterpart to the connection plate on the filling system. It is the object of the invention to create such a quick-change device which enables automatic clamping of the connection plate and connection block and which is structurally integrated into one of these two assemblies.

  • Patent number: 10479165
    Abstract: The disclosure relates to a method for operating a filling adapter for filling refrigerant R744 into vehicle air conditioning systems as well as to a corresponding adapter. The adapter comprises mechanical clamping elements actuated by a pneumatically or mechanically controlled clamping piston. The clamping elements are clamped b the clamping system onto specifically designed sections of the vehicle air conditioning system for the filling process and are kept in the clamping position during the filling process. The clamping piston comprises at least two separate piston surfaces to be subjected to the pressure of two different pressurization media, one piston surface being effectively connected to the control pressure of the filling adapter and the other piston surface being effectively connected to the filling pressure of the refrigerant.

  • Patent number: 10328767
    Abstract: A device for filling air conditioning systems with a refrigerant during final vehicle assembly, wherein the air conditioning system comprises a connection valve on its low and high pressure sides, via which the air conditioning system can be pressure tested, evacuated, and filled, which facilitates maintenance operations in the life cycle of the system, wherein said connection valves have different geometrical contours between the high and low pressure side and to ensure that only the respective approved refrigerant is filled into the air conditioning system, and wherein the filling is performed using a filling system brought via adapters into an operative connection with the connection valves on the low and high pressure sides. The device is designed to allow filling with two different refrigerants using just two adapters and still ensures that a proper refrigerant is filled into the respective air conditioning system.

  • Patent number: 10329136
    Abstract: A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose pack, electrical, pneumatic, and hydraulic lines. The filling adapter is equipped with a clamping drive housing with a stationary part and a receiving part for clamping claws. The receiving part can be operatively connected with a union nut such that, after loosening the union nut, the position of the clamping claws can be rotationally adjusted, allowing rotation of the filling adapter with respect to the container to be filled. A clamping drive housing includes a toothing, with which the receiving part for the clamping claws engages by way of a locking pin.

  • Patent number: 10167185
    Abstract: A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose packet, electrical, pneumatic, and hydraulic lines. A filling adapter according to the disclosure achieves better fluid flow properties while reducing the overall size, production costs, and weight of the filling adapter. The filling adapter is equipped with a coaxial valve in the region of the adapter head of the filling adapter, which coaxial valve, starting from the inlet cross section, is initially provided with a flow contour extending parallel to the longitudinal axis of the valve, which in the further flow course transitions into a flow contour extending at a right angle to the longitudinal axis of the valve to the outlet cross section.

  • Patent number: 9835392
    Abstract: The invention relates to a method for preventing and detecting coolant discharges from complex hydraulic systems. The aim of the invention is to configure such a method in such a way that this method in particular meets requirements for preventing/limiting the development of explosive atmospheres in working areas and for reducing measures from previously otherwise typical requirements for Ex zones. This aim is achieved in that a circuit carrying coolant is divided into small volumes that have stop valves and a relief valve, wherein a leak detection diagnosis can be carried out by means of a pressure sensor that can be integrated.

  • Publication number: 20080231852
    Abstract: A broadband light source with a sufficiently long coherence length is impinged on the optical cavity. The broadband laser light reflects from the first and second surfaces of the cavity. The two light beams, either reflected or transmitted, are phase shifted from one another by an amount proportional to the optical path length of the cavity and inversely proportional to the wavelength of the light (4?nd/?) The two light beams interfere with each other and form a modulated light beam that has a spectrum approximately like the laser's broadband spectrum multiplied by a cosine with a frequency 4?nd/?. The modulated light beam is coupled to a spectrometer that measures the intensity of the light as a function of wavelength over a range of wavelengths. The Fourier transform of the spectrum contains a peak that is related to the OPL and is located at 2*n*d where n*d is the OPL.

  • Patent number: 6241437
    Abstract: A hexapodal machining center comprising a fixed frame (1) and a support (2) which are interconnected via six struts (3) of an adjustable length. The connecting points (T1, T2, T3) of three struts on the support form a first working plane, whereas a further working plane is formed by the connecting points (T4, T5, T6) of the three further struts on the support. The frame connection points (G1, G2, G3, G4, G5, G6) of the struts are also arranged in two separate working planes. The connecting points of the two working planes of the support are superimposed such that the connecting lines of the superimposed pairs of connecting points (T1, T4; T2, T5; T3, T6) extend in parallel with each other. This allows a high degree of movability of the support in all of the six degrees of freedom. In particular, the movability in the three rotational degrees of freedom and the force receiving capacity of the support are optimized.
