PURPOSE:To perform easy adjustment of compressor volume, by providing inner rotors having spiral outer teeth meshed with inner teeth of a ring rotor and controlling speed of the ring rotor. CONSTITUTION:In peripheral surfaces of inner rotors 3a-3c, there are provided helical outer teeth 3T meshed and equally shaped to inner teeth 1a of a ring rotor 1. In case of driving a rotary casing 2, if the ring rotor 1 is fixed rated operation can be performed, and if the ring rotor 1 is rotated in a same direction as the rotary casing 2, compression work can be reduced. Accordingly, adjustment of compression volume can be easily performed by controlling speed of the ring rotor 1.
31	TWIN PISTON FLUID COMPRESSOR OR PUMP APPARATUS WITH AN ANNULAR BORE HOUSING	EP03722069	2003-05-23	EP1514028A4	2006-05-24	DAY TERENCE ROBERT
An apparatus to pump fluids comprises an annular bore (12) and at least one pair of pistons(15, 16) which travel along the bore (12). The pistons (15, 16) can be releasably locked to a rotating plate like member (14) to travel through the bore (12). One piston (15) moves with the rotating plate (14) to be the travelling piston while the other piston (16) is locked in the bore (12) to become the stationary piston. As the travelling piston hits the rear of the stationary piston, a changeover occurs where the travelling piston becomes locked to the bore (12) to become the stationary piston and the stationary piston becomes released from the bore (12) and locked to the rotating plates (14) to become the travelling piston. This arrangement is continuously repeated to provide a pump/compressor/engine and the like.

An apparatus for preventing vacuum of a scroll compressor, comprising: a fixed scroll (130) having a bypass hole (135) through which a suction chamber (51 ) of a casing (110) is connected to a discharge camber (52) of the casing (110); a valve block (151) having an inner channel through which the bypass hole (135) of the fixed scroll (130) is connected to the discharge chamber (52) of the casing, and fixedly installed at the fixed scroll (130); and a valve member (152) disposed between the bypass hole (135) of the fixed scroll (130) and the inner channel of the valve block (151 ), for opening and closing between the bypass hole (135) and the inner channel. Since the apparatus is assembled at an outer periphery of the fixed scroll (130), a processing error of the fixed scroll (130) is prevented thereby to reduce a production cost. Also, since foreign materials generated when a refrigerant channel is processed does not remain in a valve hole (155a), the valve member (152) is prevented form being mal-operated, a productivity is enhanced, and a fabrication cost is reduced.
34	LUBRICANT CIRCUIT FOR A COMPRESSOR UNIT AND PROCESSES OF CIRCULATING LUBRICANT	PCT/US1990005040	1990-09-06	WO1991005167A1	1991-04-18	UNOTECH CORPORATION; LASSOTA, Marek, Jan
A lubricant circuit and a process for circulating a lubricant through such lubricant circuit of a compressor unit (50) incorporating a compressor comprising a cylinder-piston (100) and piston (130). One embodiment of a process of this invention relies on pressure in a lubricant separator vessel (10) to force the flow of lubricant through the circuit (20, 27, 31) to the compressor, and uses a lubricant pump (158) as a scavenge pump. Another embodiment of a circuit and another embodiment of a process of this invention relies on the pressure developed by the lubricant pump (158) to force the flow of lubricant through the circuit (42, 27, 31) to the compressor, and utilizes a float (21) operated valve (22) to maintain constant lubricant level in the lubricant separator vessel. Both embodiments of the circuit may include an additional, independent circuit (25) connecting the bottom of a sump (12) of the lubricant separator vessel with a bearing manifold (36) downstream from the manifold's orifice (37) to provide for an additional flow of lubricant to the bearings of the compressor during start-up of the compressor unit.
