摘要:
A vehicle air-conditioning system provided with a refrigeration cycle system is provided. The air-conditioning system includes an evaporator outlet air target temperature setting unit which sets the target temperature of air at an outlet of an evaporator at a predetermined temperature greater than or equal to a minimum temperature which is set for preventing freezing of the evaporator. The target temperature setting unit controls the predetermined temperature to the minimum temperature when the vehicle speed is lower than or equal to a predetermined vehicle speed.

An in-wheel motor drive device (21) includes a motor part A, a reducer part B, a wheel hub C, and a reducer part lubricating mechanism to supply a lubricant oil to the reducer part. The reducer part lubricating mechanism includes a lubricant oil path (25c), a lubricant oil supply port (25d), a lubricant oil discharge port (22b), a circulation oil path (45) passing through a casing (22) to connect the lubricant oil discharge port (22b) to the lubricant oil path (25c), and to return the lubricant oil discharged from the lubricant oil discharge port (22b) to the lubricant oil path (25c), a cooling water path (22e) provided in the casing (22) so as to be in contact with the circulation oil path (45) to cool down the lubricant oil passing through the circulation oil path (45), and a partition member (49) arranged in a contact position between the circulation oil path (45) and the cooling water path (22e), to separate them.

A scroll type compressor has bypass ports which communicate with the compression chambers. The bypass ports are bored in an end plate of a stationary scroll. A capacity control block is contained inside a bypass passage which has the bypass ports communicate with a suction chamber formed in a housing. A valve mechanism which opens and closes the bypass passage is formed separately from the stationary scroll. The capacity control block is engaged with the stationary scroll and installed fixedly in the housing, thereby to control the output capacity of the compressor in a range from 0% to 100%.

A scroll-type compressor has a ring-shaped protruding portion of a front case is fitted into an opening end of a case body so as to construct a housing, a stationary scroll and a revolving scroll which are engaged with each other when they are disposed in the housing. The stationary scroll is fixed to the housing, and at the same time, the revolving scroll is made to revolve in solar motion by a revolution drive mechanism from a rotary shaft while checking rotation on its axis of the revolving scroll by a rotation check mechanism. More particularly, a compressor in which a gas suction port is opened at a location where the ring-shaped protruding portion of the case body is engaged and at least one and more draught holes including a through hole which penetrates to the inside opposing to the suction port are provided on the ring-shaped protruding portion. It is thereby possible to improve cooling and lubrication of the rotation check mechanism and the revolution drive mechanism.

摘要:
A pin passing through a pin hole disposed in a support portion disposed on a rotating shaft is fixed to the support portion by fitting a first push nut to the pin so that the first push nut abuts against the top surface of the support portion. Then, a balance weight is supported by the support portion by fitting a second push nut onto the protruding end of the pin.

A speed detector of a scroll-type fluid machine in which a fixed scroll and an orbiting scroll, each of which includes a spiral wrap disposed on the inner surface of an end plate thereof, are engaged with each other and housed in a closed housing, and the orbiting scroll revolves while its rotation is checked by means of an Oldham's ring having the orbiting scroll disposed on the outer surface thereof, wherein the Oldham's ring is formed of a magnetic material, and an electromagnetic induction type revolution signal detecting means is installed in an opposed relationship to the Oldham's ring.

A scroll type fluid machinery has a stationary scroll and a revolving scroll having spiral wraps set up on inner surfaces of respective end plates in engagement with each other. A drive bushing is inserted rotatably into a boss which is projected at a central part of an outer surface of the end plate of the revolving scroll. An eccentric driving pin of a rotary shaft is fitted slidably into a slide groove bored through the drive bushing. A gap between one end of the slide groove in a direction that the radius of revolution becomes larger and the eccentric driving pin is set to a preset very small distance .delta. (here, .delta. is a value determined based on processing error, deformation due to temperature and pressure and the like of the above-mentioned respective scrolls) when the revolving scroll occupies a position of theoretical radius of revolution thereof. With this, it is possible to prevent the drive bushing from tiltably rotating beyond what has been predetermined while the revolving scroll is revolving.

A scroll type fluid machinery provided with a slide type radius of revolution variable mechanism prevents unilateral working of a rotating bearing 23 due to tilted rotation of a drive bushing 21 and a balance weight 27 fixed thereto. A bolt 41 for regulating tilted rotation is projected at an inner end of a rotary shaft 7, a shaft portion 41a therefor penetrates through a hole 42 bored in the balance weight 27, and a bearing surface 41c of a head 41b thereof is brought into slidable contact with the inner end surface of the balance weight 27. When the radius of revolution is varied at the time of revolution in a solar motion of a revolving scroll 14, an eccentric driving pin 25 slides in a slide groove 24 and the shaft portion 41a of the bolt 41 slides in hole 42 at the same time. In the interim, the bearing surface 41c of the head into slidable contact with the inner end surface of the balance weight 27, thereby to suppress tilted rotation of the balance weight 27.
