Abstract: A variable capacity wobble plate compressor of the type that a wobble plate mounted on a drive shaft is swung axially of the drive shaft as the drive shaft rotates, and pistons connected to the wobble plate make reciprocating motions in response to swinging of the wobble plate, wherein a change in the angularity of the wobble plate causes a change in stroke of the reciprocating motions of the pistons whereby the capacity of the compressor is varied. A sensing element arranged on the wobble plate is moved along a predetermined orbital path together with swinging of the wobble plate. A sensor arranged on a compressor housing generates an electric signal when the sensing element passes by the sensor as the wobble plate swings. A control unit determines the rotational speed of the compressor and the angularity of the wobble plate on the basis of the electric signal from the sensor. The sensor is so located as to align with a predetermined location between an axial center of the predetermined orbital path of swinging of the sensing element and an extreme possible point toward the pistons, when the wobble plate assumes the minimum angularity.

Abstract: Disclosed is a device for controlling or measuring operational parameters of an axial piston machine. The tilting plate which engages and adjusts the stroke of the piston is provided with two opposite pivot pins supported in fixed bearings. At least one pivot pin is provided with a shearing stress sensor preferably in the form of a magnetoelastic feeler which produces electrical signals the pulsation of which is indicative of rotational speed and the magnitude of the signal is proportional to pressure applied by the pistons and thus to the delivery of the machine. A second sensor is coupled to the tilting plate to indicate the angular displacement of the latter. The output signals from the sensors are separated into the pressure dependent signals, frequency dependent signals and angular displacement signals which upon multiplication are applied to a programmable data processing unit. The output of the unit is supplied to a solenoid operated proportional valve which controls pressure fluid for hydraulic setting motors which adjust the angular displacement of the tilting plate.

Abstract: PURPOSE:To monitor the operation state of a slanting plate type compressor by making a cylinder block, having a slanting plate chamber, of a nonmagnetic material, and by making a slanting plate of a magnetic material as a part to be detected. CONSTITUTION:As a driving shaft 3 coupled with a power source turns a slanting plate 5 stuck to it to reciprocate a piston 8 in a cylinder bore 4, thereby compressing a fluid to be compressed. Through the turning of the driving shaft 3, a detected part consisting of the circumferential part of the slanting plate 5 moves on a periodic motion track and when the detected part confronts to a magnet 20, magnetic flux changes in density to generate a currnt at a coil 21 surrounding the magnet 20. Then, when a pulse-existence detector supplied with the said output detects no set time pulse existing, an electromagnetic clutch coupling the driving shaft with the power source is placed in a released state. Thus, the driving source and its relative equipments are protected.

Abstract: PURPOSE:To protect driving system apparatus by providing a magnetic body on the outside circumference of a swash plate thereby generating periodic pulses in an electromagnetic sensor, and stopping the driving of a compressor when abnormality occurs therein. CONSTITUTION:A metallic ring 17 constituting a part to be detected is fitted to the outside circumference of a swash plate 5 of a non-magnetic material making oscillatory motion within a swash plate chamber 24, and an electromagnetic sensor 18 is disposed on the cylinder block 1, 2 sides in the position opposing periodically to a part of the ring 17. The sensor 18 opposes to the axial central part of the rotating locus of the ring 17, and opposes the ring 17 twice in one turn of the swash plate 5. When a driving shaft 3 revolves, the swash plate 5 revolves and a piston 8 moves back and forth in a cylinder bore 4, whereby the compression action of the fluid to be compressed is effected. The sensor 18 generates voltage pulses at the periods corresponding to the rotating speeds of the shaft 3, and when the compressor stops abnormally, the signal of driving input interruption is outputted from a pulse presence or absence detector, whereby the driving of the compressor is stopped.
