Claims

[Scope of Claim for Utility Model Registration] (1) In an internal gear type pump in which an inner rotor and an outer rotor synchronously rotate and mesh with each other in the same direction, the working chamber and the suction side of the internal gear type pump are connected to each other. A control valve having a control part that changes a communication cutoff timing, and a sub-control valve having a sub-control part that changes a communication start timing between the working chamber and the discharge side of the internal gear type pump, and the control valve and the control part. The auxiliary control section is provided so as to be in close contact with or in contact with the rotor, and by operating the control valve, changes the timing of shutting off the construction between the working chamber and the suction side of the internal gear type pump, A capacity control device for an internal gear type pump, characterized in that the time at which communication starts between the working chamber and the discharge side of the internal gear type pump is changed by operating the sub-control valve. (2) Claim No. 1 for utility model registration, which is a supercharger in which an internal gear type pump is connected to the output shaft of an internal engine.
A capacity control device for an internal gear type pump as described in . (3) By operating the control valve and the auxiliary control valve to their respective predetermined positions, the working chamber and the turbocharger's discharge side close to the point where the communication between the working chamber and the suction side of the supercharger is cut off. The structure is configured so that communication with the supercharger starts, and the pressure on the suction side of the supercharger is greater than the pressure on the discharge side, thereby generating power for the supercharger, and from the above state. A capacity control device for an internal gear type pump according to claim 2, which is configured to further supply air to the engine when more air is required to be supplied to the engine. (4) Focusing on the supercharger connected to the output shaft of the engine,
A supercharger is installed on the upstream side of the supercharger to increase pressure using exhaust gas energy, and when the pressure on the upstream side of the supercharger exceeds a specified value, a control valve is activated to control the capacity of the supercharger. A capacity control device for an internal gear type pump according to claim 2 or 3 of the utility model registration claim.
