    Abstract: PURPOSE:To improve the stability of signals, increase the change in magnetic flux density and perform accurate controlling with high sensitivity by so arranging the device that a swash plate as a part to be detected makes motion of relatively large moving distances and speeds and that pulse signals of twice are generated by one turn of the swash plate. CONSTITUTION:The part to be detected is formed by the circumferential part per se of a swash plate 5 which is oscillating in a swash plate chamber 22. An electromagnetic sensor 17 is disposed in the shell part of a cylinder block 1, in a position opposite to two points having a 180 deg. phase difference in the detecting part and having the same rotating locus, that is, a position opposite to the part A corresponding to the axial central part of the rotating locus of the circumferential part with the swash plate 5. In this way the sensor 17 generates periodic pulse signals in association to the movement of the swash plate 5. The abnormal stoppage of the compressor is detected from the absence of these pulse signals, and the connected state with a driving system can be released immediately, and therefore the driving system and the apparatus and the like associating to this are protected.

    Abstract: This compressor includes housing members that form a body; a drive shaft linked to a drive power source via an electromagnetic clutch; movable members moving in cooperation with the drive shaft and carrying out the compression of a fluid; a detected body moving in cooperation with the drive shaft; a drain bolt screwed into a drain bolt hole provided in a housing member in proximity to the detected body; and a detecting device detecting the rotation state of the drive shaft by the detected body. The drain bolt is provided with a permanent magnet, the detecting device is structured by a magnetic sensor that includes a magnetic impedance element, and the magnetic sensor is provided at the head portion of the drain bolt. Thereby, it is possible to provide a rotation detecting mechanism by using an existing drain bolt, without requiring the machining of a hole in the compressor body.

    Abstract: The invention relates to an axial piston compressor, in particular, a compressor for the air conditioner on a motor vehicle, comprising a housing (10) and a compressor unit driven by a driveshaft (11) for the intake and compression of a refrigerant, whereby the compressor unit comprises pistons (13) running axially back and forth in a cylinder block (12) and an eccentric disc (14) rotating with the driveshaft (11). The eccentric disc (14) is provided with an additional mass, particularly in the form of an additional disc or an additional ring (15) by means of which a deviating moment which balances out the deviation moment of the eccentric disc (14) is obtained, such that the sum (MSW) of the tipping moments (MSW1+MSW2) as a result of said deviation moments is greater than or equal to the moment (Mk,ges) due to all translationally moving masses, in particular the pistons (13) or similar.

    Abstract: @ A refrigerating compressor has a rotation detecting device which comprises a magnetic pickup (24) and a rear thrust race (20) which forms part of a needle roller thrust bearing (20). The rear thrust race (23) has two tab portions (232) and a projecting portion (233) and is disposed on the rear surface of a wobble plate (8). The magnetic pickup (24) is disposed on a cylindrical housing (1) of the compressor at a position adjacent the path of movement of the rear thrust race moving with the wobble plate. The magnetic flux leaking from an electromagnetic clutch mounted on the compressor flows to the rear thrust race (23) through a drive shaft (17) and bevel gear (14). When the projecting portion of the rear thrust race is close to the magnetic pickup, a magnetic flux is produced. The magnetic pickup detects the magnetic flux. Therefore, the movement of the compressing member of the compressor is detected by the magnetic pickup. As a result, when the compressing member of the compressor is locked, the clutch can be deactivated to stop the compressor quickly.

    Abstract: 【課題】既製品の安価なモーターを用いながら吐出流量を検出可能なダイヤフラムポンプを提供する。 【解決手段】変形部12を有するダイヤフラム4と、変形部12と協働してポンプ室23を形成する底壁8(ポンプ本体部)とを備える。変形部12に取付けられた腕部26b(往復運動部)と、モーター2の回転軸5が接続されるクランク25(入力部)を有し、クランク25の回転が往復運動に変換されて腕部26bが往復する駆動機構24を備える。ポンプ室23の容積が増大することによりポンプ室23内に流体が吸入され、ポンプ室23の容積が減少することによりポンプ室23内の流体が吐出されるポンプ機構を備える。腕部26bを検出対象として構成され、腕部26bが往復運動をすることにより検出状態と非検出状態とが交互に切り替わる計数用センサ11を備えた。 【選択図】 図1
