【発明の詳細な説明】
本発明は圧縮機のピストンをカムにより作動さ
せる電動圧縮機に関し、前記カムの適正な作動曲
線設定により、圧縮機の負荷変動を押え、効率化
を目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric compressor in which a piston of the compressor is actuated by a cam, and an object of the present invention is to suppress load fluctuations of the compressor and improve efficiency by setting an appropriate operating curve of the cam.
従来の圧縮機は往復動式の場合、ピストンの運
動が正弦波運動に限定されているため、圧縮負荷
の均等化という点で制約を受けるものであつた。 In the case of a conventional compressor of the reciprocating type, the motion of the piston is limited to a sine wave motion, and therefore there are restrictions in terms of equalizing the compression load.
本発明はピストンをカムにて往復作動させるカ
ムの上死点位置が下死点に対して180度を超える
位置、即ち圧縮工程を長く設定することにより、
上記従来の制約を解消するものである。 In the present invention, the piston is reciprocated by a cam, and the top dead center position of the cam exceeds 180 degrees from the bottom dead center, that is, by setting the compression stroke to be long,
This eliminates the above-mentioned conventional restrictions.

固定されている。 In the figure, 1 is a casing, and 2 is a motor stator press-fitted into the casing. A bearing metal 3 holds the camshaft 4 press-fitted into the motor rotor 2a. Further, 5 is a cam surface formed on the camshaft 4. In this case, the top dead center of the cam curve 5a of the cam surface 5 is set at a position exceeding 180 degrees from the bottom dead center. A cylinder 6 is fixed to the bearing metal 3 and has an axis parallel to the axis of the camshaft 4, and a piston 7 is slidably disposed within the cylinder. One end of the piston 7 is provided with a roller pin 9 having a roller 8 at its tip (lower end), and the roller 8 engages with the cam surface 5. Further, one end of the roller pin 9 (upper end) extends into a guide 10 provided in a part of the cylinder 6. 11 is a valve plate, and 12 is a cylinder head. 13 is a suction pipe provided at the end of the casing 1, 14 is a discharge pipe, and 15 is a discharge chamber. 16 is oil stored at the bottom of the casing 1, 17 is an oil fan fixed to the camshaft 4,
Reference numeral 18 denotes an oil buffer, which is fixed to the discharge chamber 15.
カム面５のカム曲線５ａは、第２図の展開図に

上死点まで）に対応するカム曲線は回転角度0゜か
ら210゜にわたつており、一般のピストン・コンロ
ツドタイプの0゜から180゜に比べて圧縮工程の回転
角度より大きくしてある。 The cam curve 5a of the cam surface 5 corresponds to the compression stroke (from the bottom dead center to the top dead center) of the piston 7, as shown in the developed view of FIG. 2, over a rotation angle of 0° to 210°. The angle of rotation is larger than that of the compression process, compared to the 0° to 180° angle of general piston/conrod types.
また吸入工程の回転角度は210゜から360゜であ
る。尚、圧縮工程とと吸入工程のストローク変化
状態は各々近似正弦曲線である。 The rotation angle of the suction process is 210° to 360°. Note that the stroke change states of the compression stroke and the suction stroke are each approximate sinusoidal curves.

れる。 In the above configuration, when the cam surface 5 rotates by energizing the motor 2, the piston 7 reciprocates inside the cylinder 6 according to the cam curve 5a due to the roller 8 and roller pin 9 engaged with the cam surface 5.
At the same time, the oil fan 17 also rotates, and together with the oil baffle 18, oil 16 is supplied to the fitting sliding portion inside the casing 1. During this time, gas sucked in from outside the casing 1 by the operation of the piston 7 flows into the cylinder 6 through the suction pipe 13 and is compressed, and is discharged out of the casing 1 through the discharge pipe 14 again.

ことにより、吸入工程に比べて負荷の大きな圧縮

きくとれるため、所用トルクの低減を計れ、電動
モータ入力を下げ性能の高効率化が得られる。 Therefore, by setting the top dead center position of the cam curve 5a formed on the cam 4 to a position exceeding 180 degrees from the bottom dead center, the compression process, which has a larger load compared to the suction process, can be performed at a rotation angle that is different from the conventional one. Since the torque can be larger than that of conventional motors, it is possible to reduce the required torque, lower the electric motor input, and improve performance efficiency.

下げてエネルギ消費効率を向上できる。 As is clear from the above explanation, in the electric compressor of the present invention, the top dead center position of the piston actuating cam is set to a position exceeding 180 degrees from the bottom dead center.
It is possible to reduce torque during the compression process, lower motor input, and improve energy consumption efficiency.
