The invention relates to a primary gasket (1) for a cylinder assembly (100), in which the cylinder assembly (100) comprises a cylinder (101) and a float (102) housed in a sliding manner in a float housing (104) delimited by a cylinder wall (103) of the cylinder (101) to pressurize a fluid, in which the primary gasket (1) comprises an annular body (2), the annular body (2) extends in a circumferential manner at least along a circumferential direction (C-C) around the axial direction (X-X), where the primary gasket (1) defines a radial direction (R-R) perpendicular to the axial direction (X-X) and the circumferential direction (C-C), where the annular body (2) is configured to be housed in a primary gasket housing (105) defined in the cylinder wall (103), where the annular body (2) is configured to be housed in the primary gasket housing (105). The primary gasket receptacle (105) is delimited radially by an axial receptacle wall (107) and axially by a first radial receptacle wall (108) and a second radial receptacle wall (109), the first radial receptacle wall (108) and the second radial receptacle wall (109) being connected to the axial receptacle wall (107), the annular body (2) comprises an inner lip (4), a central lip (5), an outer lip (6) and a back portion (3), where the back portion (3) comprises a back abutment surface (13) configured to abut against a first radial receptacle wall (108) of the primary gasket receptacle (105), where the back abutment surface (13) is configured to abut against a second radial receptacle wall (108) of the primary gasket receptacle (105). The inner lip (4), the central lip (5) and the outer lip (6) extend axially from the back portion (3) on a side opposite to the back abutment surface (13) and are radially spaced apart from one another, where the inner lip (4) is configured to form a seal with the float (102), where the outer lip (6) is configured to form a seal with the axial receptacle wall (107), where the inner lip (4) is configured to form a seal with the float (102) and the central lip (5) is configured to form a seal with the axial receptacle wall (107). The central lip (5) comprises an annular lip body (14) extending axially between the back portion (3) and a central lip edge (15), where the annular lip body (14) has a central lip thickness (S) in a radial direction (R-R), where the central lip edge (15) comprises at least one central lip abutment portion (7), where the central lip abutment portion (7) has a central lip thickness (S) in the radial direction (R-R). The at least one central lip abutment portion (7) is configured to abut against the second radial wall (109), where the central lip (5) comprises at least one radial opening (9), where the at least one radial opening (9) passes through the central lip thickness (S), thereby defining a closed side opening profile (8) in the annular body (14).
本发明涉及一种用于缸组件(100)的初级衬垫(1),其中,缸组件(100)包括缸(101)和浮动件(102),浮动件(102)以滑动的方式容置在由缸(101)的缸壁(103)界定的浮动件容纳部(104)中,以对流体进行加压,其中,初级衬垫(1)包括环形本体(2),环形本体(2)至少沿着围绕轴向方向(X‑X)的周向方向(C‑C)以周向的方式延伸,其中,初级衬垫(1)限定径向方向(R‑R),径向方向(R‑R)垂直于轴向方向(X‑X)和周向方向(C‑C),其中,环形本体(2)被构造成容置在被限定在缸壁(103)中的初级衬垫容纳部(105)中,其中,初级衬垫容纳部(105)在径向上由轴向容纳部壁(107)界定并且在轴向上由第一径向容纳部壁(108)和第二径向容纳部壁(109)界定,所述第一径向容纳部壁(108)和所述第二径向容纳部壁(109)连接到轴向容纳部壁(107),其中,环形本体(2)包括内部唇部(4)、中央唇部(5)、外部唇部(6)和背部部分(3),其中,背部部分(3)包括背部抵接表面(13),背部抵接表面(13)被构造成抵靠初级衬垫容纳部(105)的第一径向容纳部壁(108),其中,内部唇部(4)、中央唇部(5)和外部唇部(6)在与背部抵接表面(13)相对的一侧上在轴向上从背部部分(3)延伸并且在径向上彼此间隔开,其中,内部唇部(4)被构造成与浮动件(102)形成密封,其中,外部唇部(6)被构造成与轴向容纳部壁(107)形成密封,其中,中央唇部(5)包括环形唇部本体(14),环形唇部本体(14)在轴向上在背部部分(3)与中央唇部边缘(15)之间延伸,其中,环形唇部本体(14)具有沿径向方向(R‑R)的中央唇部厚度(S),其中,中央唇部边缘(15)包括至少一个中央唇部抵接部分(7),至少一个中央唇部抵接部分(7)被构造成抵靠第二径向壁(109),其中,中央唇部(5)包括至少一个径向开口(9),其中,至少一个径向开口(9)穿过中央唇部厚度(S),从而限定环形本体(14)中的封闭的侧开口轮廓(8)。
