摘要:
A displacement type fluid machine in which a displacer and a cylinder are disposed between end plates, a space is formed by an inner wall surface of the cylinder and an outer wall surface of the displacer when the center of the displacer is put on the center of the cylinder, and a plurality of spaces is formed when the positional relationship between the displacer and the cylinder is for a gyration, is restrained from deterioration of the efficiency. One of the end plates and a vane protruding inwardly from the inside surface of the cylinder are fixed to each other so as to restrain the deformation of the vane and decrease the leakage of a working fluid due to the deformation.

Fixed scrolls 4, 5 are supported so to be movable axially relative to an orbiting scroll 6, so that a proper space is kept between wraps 4a, 5a and 6a to avoid an excessive load in the contacting area. Further, an end portion of an outer curve of the wrap 6a of the orbiting scroll 6 is formed to come close to or coincide to an outer edge of a panel 6f of the orbiting scroll 6 and an Oldham's coupling is accommodated in a concave groove 6e formed on an outer circumference surface of the panel 6f, so that the size of the scroll compressor is reduced.

A scroll type fluid machine includes a lever 26 moved to draw a conical locus so that revolution is given to an orbiting scroll member 2, to thereby lower a sliding load and a sliding speed of a sliding portion on which a load is acted in a radial direction by the above principle. Further, the orbiting scroll member is supported in a thrust direction by a thrust force transmission member 50 interposed between the orbiting scroll member 2 and a fixed scroll member 1 to thereby lower a sliding speed of the sliding portion on which a load is acted in the thrust direction. With this arrangement, a scroll type fluid machine having high efficiency and durability can be provided.

An automatic urine disposal device has a urine collecting pad, vacuum pump, and urine tank. In the urine collecting pad, the top sheet comes in contact with the wearer's skin, the hydrophilic sheet is disposed on the bottom of the top sheet, and the urine absorbent sheet is disposed at the bottom. When discharged urine flows in the top sheet, the hydrophilic sheet widely diffuses urine to saturate its entire surface and then becomes non-breathable. As the vacuum pump vacuums the air from the urine tank, urine is directed from a urine drainage port of the urine collecting pad via a urine drainage tube to the urine tank which is a sealed container.

A scroll compressor has an orbiting scroll which operatively meshes with a stationary scroll to define compression chambers therebetween. This orbiting scroll is driven by an electric motor through a crank-shaft, and makes an orbiting movement while being prevented from rotating about its own axis by a rotation preventing member. The crankshaft is journalled by at least two sliding bearings which are arranged respectively on the both sides of the electric motor, and the mast remotely distanced bearing from the orbiting scroll has a self-aligning function which enables it to change its attitude in accordance with any inclination of the crankshaft. Further, a balance and a counter weight are provided on the crankshaft to counterbalance the centrifugal force produced by the orbiting scroll and the inertial force produced by the rotation preventing member.
摘要:
A motor-driven compressor used as a compressor or high-pressure gas generator for a refrigerating cycle, in which the output torque of the electric motor for driving the compressor is controlled so as to make the output torque agree with the load torque required for performing compression in any revolutional angular position of the driving main shaft to thereby reduce revolutional torsional vibrations caused by disagreement between the load torque and the output torque.
摘要:
In a double toothed type scroll compressor, spiral wraps are formed on both sides of an end plate of an orbiting scroll, and wraps adapted to engage with the spiral wraps are formed on a stationary scroll. A dust wrap is formed on a side diametrically outside of the wrap of the stationary scroll. Grooves are formed on ends of the respective wraps to receive therein seal members formed of a high polymer material. Electric charge of static electricity produced when the seal members slide on surfaces of the mating end plate is made to flow from a bolt provided on an end of a crankshaft to the stationary scroll through a brush, thereby preventing accumulation of electric charge in a crankshaft.
