Abstract: A sensor assembly includes a body having a guide surface. A sensor head is mounted to the body. An elongated sensing element has a first end connected to the sensor head and a second end extending away from the first end along the body along a path of measurement. A first portion of the elongated sensing element extends from a sensor head bends by the guide surface so as to align a second portion of the sensing element with the path of measurement. A member is positionable along the path of measurement adjacent the second portion of the sensing element.

Abstract: A motor or pump includes a stator and a rotor supported for rotation with respect to the stator by a bearing arrangement. The rotor has a cylinder block thereon having radial cylinder bores equipped with radially reciprocable pistons. Rollers on the pistons abut a cam ring fixed to the stator so that the pistons to reciprocate radially to displace fluid when the rotor turns relative to the stator. The stator includes a control device fixed thereon having a pair of fluid passages therein. One side of the control device constitutes a distribution face with outlets therein connecting the fluid passages to the cylinder bores as the rotor rotates. A counterpart fastens to the rotor adjacent the opposite side of the control device so as to define an annular chamber therebetween. A shuttle valve operatively interposed between the passages and chamber ensures that the chamber remains in connection with the passage having the higher pressure.

Abstract: The hydrostatic motor of this invention includes a fluid pressure unit having a stator and a rotor. The rotor includes a cylinder block containing a plurality of radially disposed cylinder bores therein. At one end, close to the axis of the rotor's rotation, each of those cylinders is connected to a corresponding bore extending substantially in axial direction. Therefore, the center lines of the outlets of all bores are disposed on the same pitch diameter on the front face of the cylinder block. On this front face a distribution face of the cylinder block is provided containing said outlets. A lobed cam ring is fixed to the stator. Each cylinder bore houses a roller abutting the cam ring and thereby reciprocating a piston radially within the bore in response to the lobes of the cam ring. A control device is provided as a part of the stator.
