    • PURPOSE: A scroll type compressor is provided to improve the controllability and the responsibility of a backpressure control valve. CONSTITUTION: A scroll type compressor comprises a housing, a fixed scroll, a movable scroll, a suction chamber(42), a compression chamber, an ejection chamber(47), and a back pressure chamber(39). The fixed scroll and the movable scroll are pressurized each other by the back pressure within the back pressure chamber. A back pressure control valve(72) is formed between the ejection room or compression room and the back pressure chamber and/or between the back pressure chamber and the suction chamber. The back pressure control valve comprises a first valve room(74a) which is communicated with the ejection room or the compression room by a high pressure path, a second valve room(74b) which is communicated with the back pressure chamber by a back pressure path, a third valve room(74c) which is communicated with the suction chamber by a low pressure path, a first pressure receiving surface(S1) which is located within the first valve room, a second pressure receiving surface(S2) which is located within the second valve room, and a third pressure receiving surface(S3) which is located within the third valve room. The pressure receiving area of the third pressure receiving surface is larger than the pressure receiving area of the first pressure receiving surface and the pressure receiving area of the second pressure receiving surface.
    • 目的:提供一种涡旋式压缩机,以提高背压控制阀的可控性和责任感。 构成:一种涡旋式压缩机,包括壳体,固定涡旋件,可动涡旋件,吸入室(42),压缩室,喷射室(47)和背压室(39)。 固定涡旋件和动涡旋盘通过背压室内的背压相互加压。 在喷射室或压缩室与背压室之间和/或背压室与吸入室之间形成背压控制阀72。 背压控制阀包括通过高压路径与喷射室或压缩室连通的第一阀室(74a),通过背压路与后压室连通的第二阀室(74b) ,通过低压路与吸入室连通的第三阀室(74c),位于第一阀室内的第一受压面(S1),位于第一阀室内的第二受压面(S2) 第二阀室和位于第三阀室内的第三受压面(S3)。 第三受压面的受压面积大于第一受压面的受压面积和第二受压面的受压面积。

    • A swash plate type compressor that has a pair of shoes (18A, 18B, 18C, 18D, 18E) between a swash plate (15) and a piston (17). The motion of the swash plate is transmitted to the piston through the shoes. Each piston reciprocates according to the transmitted motion. A coating (32, 33) is applied to each surface of the swash plate to contact the corresponding shoe. The surface (H) of each coating (32, 33) is flat. Each shoe (18A to 18E) includes a substantially flat surface (34), which contacts the swash plate (15), and a semi-spherical portion (35), which is fitted to the piston (17). Each substantially flat surface (34) includes a main chamfered portion (342) near the periphery. The inclination angle (&thetas; 1) of each main chamfered portion (342) with respect to the corresponding coating is a predetermined angle or less. Each coating contacts one of the substantially flat surfaces (34). The maximum distance ( beta ) between each main chamfered portion (342) and the corresponding coating is equal to or less than the thickness (D) of the corresponding coating (32, 33).
    • 一种斜盘式压缩机,其在斜板(15)和活塞(17)之间具有一对滑靴(18A,18B,18C,18D,18E)。 斜盘的运动通过鞋传递给活塞。 每个活塞根据传递的运动进行往复运动。 涂层(32,33)被施加到斜盘的每个表面以接触相应的滑靴。 每个涂层(32,33)的表面(H)是平坦的。 每个滑瓦(18A至18E)包括与斜盘(15)接触的基本上平坦的表面(34)和装配到活塞(17)上的半球形部分(35)。 每个基本平坦的表面(34)包括靠近周边的主倒角部分(342)。 每个主倒角部分(342)相对于相应涂层的倾角(θ1)为预定角度或更小。 每个涂层接触基本平坦的表面(34)中的一个。 每个主倒角部分(342)与相应涂层之间的最大距离(β)等于或小于相应涂层(32,33)的厚度(D)。 <图像>
