To provide a liquid pressure unit which is constituted to be compact and inexpensive, and which comprises a buffer mechanism for buffering pressure pulsation of a pressure generator that can be easily mounted.SOLUTION: Well-known liquid pressure units each comprise a pressure generator. However, the pressure generator causes pressure pulsation. In order to buffer the pressure pulsation, a buffer mechanism is used. According to a proposal of the present invention, a throttle element (70) abuts on a first support body (74a) using an upper surface and abuts on a second support body (74b) using a lower surface, in a state that pressure is not acting thereon. The support bodies (74a and 74b) are formed on mutually opposing sides of a gap (72). Advantageously, the throttle element (70) does not have to be provided with an elastic element for pre-tensioning itself in an axial direction.SELECTED DRAWING: Figure 1

    【課題】コンパクトに且つコスト上好ましく構成され、さらに取り付けが容易である圧力発生器の圧力脈動を緩衝するための緩衝機構を備えた液圧ユニットを提供する。【解決手段】公知の液圧ユニットは圧力発生器を備えているが、前記圧力発生器は圧力脈動を生じさせる。この圧力脈動を緩衝するため、緩衝機構が使用される。本発明の提案によれば、絞り要素(70)は、圧力の作用を受けない状態で、上面でもって第1の支持体(74a)に当接し且つ下面でもって第2の支持体(74b)に当接し、前記支持体(74a,74b)は、前記隙間(72)の、互いに対向しあっている側に形成されている。有利にも、前記絞り要素(70)は、自らを軸線方向に予緊張させるための弾性要素を設けずに済む【選択図】図1
