The invention provides a scroll compressor which comprises a crankshaft, an upper end ring and a balance block, wherein the crankshaft is internally provided with a through eccentric through hole, and the side wall of the crankshaft is provided with an inclined oil channel; the upper end ring is fixedly connected with the crankshaft, the upper end ring is provided with an oil channel connecting part matched with the inclined oil channel, and the inclined oil channel is communicated with the eccentric through hole and the oil channel connecting part; the balance block is fixedly connected with the upper end ring and the balance block is provided with an oil deposition part communicated with the oil channel connecting part. According to the scroll compressor, partial lubricating oil reflowing from a main support frame is intercepted, is stored in the oil channel connecting part and the oil deposition part and is conveyed through the inclined oil channel of the crankshaft, so that the lubricating oil can be sufficiently supplied to all parts needing to be lubricated, the defect that the lubricating oil is supplied from the lower end of the crankshaft is overcome, the time of supplying oil upwards to the compressor is shortened, and the oil supply capability of the compressor is improved.

The invention discloses a pulse oil-supply type oil duct of an engine cylinder body. The structure of the pulse oil-supply type oil duct of the engine cylinder body is as follows: a cam shaft bushing is arranged inside a cam shaft bearing hole on the engine cylinder body; a section of an oil tank and an oil outlet are arranged on the cam shaft bushing; and a T-shaped oil hole is processed on the cam shaft. The oil tank and the oil outlet on the cam shaft bushing are respectively communicated with the cam shaft and a rocker arm oil supply channel when the cam shaft rotates to a certain position; a main oil duct can supply oil to a crank bearing, the cam shaft and a rocker arm at the same time. The oil tank on the cam shaft bushing is communicated with an oil supply branch channel of the cam shaft, but the oil outlet on the cam shaft bushing cannot be communicated with the oil supply channel of the rocker arm when the cam shaft rotates to deviate from the position. By ingenious designs of the cam shaft bushing and the cam shaft, the cam shaft can finish twice and two paths of oil supply with different oil supply quantities after rotating a circle. Lubrication of the rocker arm can be achieved, at the same time the pressure of the main oil duct is basically constant, and parts such as a crank, the cam shaft and the like are guaranteed to be fully lubricated.

The invention relates to an oil supply device for a linear compressor. The oil supply device comprises first and second grooves which are buckled with each other and clamp an elastic film therebetween, and a first end cover covering on an outer surface of the bottom of the first groove; the first and second grooves and the elastic film enclose to form a first cavity and a second cavity respectively; an oil supply through hole and an oil absorption through groove are formed at the bottom of the first groove; the first end cover is provided with an oil supply blind groove and an oil absorption through hole; the oil absorption through hole is communicated with the oil absorption through groove, and an end surface where the oil absorption through hole is communicated with the oil absorption through groove is provided with a one-way oil absorption valve opened toward a direction close to the first cavity; the oil supply through hole is communicated with the oil supply blind groove, and an end surface where the oil supply through hole is communicated with the oil supply blind groove is provided with a one-way oil supply valve opened toward a direction away from the first cavity; the centre of the elastic film is connected with a moving component of the compressor or provided with a balance weight. When the linear compressor works, the elastic film reciprocates so as to change the volume of the cavity; if the volume of the cavity is larger, negative pressure is generated in the cavity, so that the oil absorption valve is opened and the oil enters the cavity; and if the volume of the cavity is smaller, the pressure in the cavity is increased, so that an oil discharge valve is opened and the oil enters a cylinder of the compressor.
