ABSTRACT:
A hydraulic torque impulse mechanism intended for a torque delivering tool and including a rotatively driven drive member (10) provided with a concentric fluid chamber (12) and radially acting cam elements (25, 26, 28), an output shaft (16) extending through the drive member (10) fluid chamber (12) and having two radial cylinder bores (18, 19) which communicate continuously with a central high pressure chamber (23) and support two piston elements (20, 21) which are reciprocable in the cylinder bores (18, 19) by the cam elements (25, 26, 28), whereby the output shaft (16) comprises two moderating chambers (45, 46) which communicate continuously with the high pressure chamber (23) and comprise a pressure responsive yielding system in the form of membranes (50) which are supported by end closures (47) of the moderating chambers (45, 46) and which are elastically deformable by the pressure difference between the high pressure chamber (23) and the fluid chamber (12) as this pressure difference is below a certain level only.
