    摘要: An injection element for a combustion component running on two propellants, includes a first, central injection channel, which is connectable to a first propellant supply for a first propellant, and a second injection channel, which annularly surrounds the first injection channel. The second injection channel is connectable to a second propellant supply for a second propellant. The injection element includes a third injection channel, which annularly surrounds the second injection channel and which is in fluid communication with the first injection channel.

    摘要: A deep bucket (1) for exchangeable mounting at the jib head of a bucket excavator consists of three shells (2, 31, 32), which are movable relative to each other and constrainedly guided towards each other. The width of the deep bucket (1) is steplessly adjustable between a minimum value and a maximum value. At least two double scissors systems (5, 6; 7, 8) are provided for the actuation and for the parallel constrained guidance of the side shells (31, 32) in each adjusted spacing.
